If the foil-wrapped Ketostix, rather than the ones in vials are purchased, you may find it less wasteful. Some reasons for preferring testing glucose levels by using blood over urine testing is that the urine used in testing may have been in the bladder for hours. Urine testing [6] also makes it more difficult to determine whether any hyperglycemia noted is the result of a Somogyi rebound pattern or a true need for an increase in insulin dosage. It's important to time the test accurately and not take into account any color changes on the Ketostix strip which occur after 15 seconds.
In a diabetic, any urinary ketones above trace, or any increase in urinary ketone level, or trace urinary ketones plus some of the symptoms above, are cause to call an emergency vet immediately, at any hour of the day.
If you are testing urine for glucose, the time you test likely affects results in this way: mid-day urine glucose tests would reflect the nadir of glucose in the system--this also represents the peak of the insulin. When the bg readings are high enough to produce some ketones, you've taken action to bring them down and they are normal once more, it is possible to still see some positive urine ketone test results.
If your pet is taking any type of vitamin supplements, it should be noted on his or her medical records. Because most urine tests measure acetoacetic acid, and not the most commonly found beta-hydroxybutyrate acid, it is possible to have ketones present and get a negative urine test result.
Further, it's also possible to have high levels of beta-hydroxybutyrate acid, get a negative urine ketone test result, but to have the test turn positive as the ketosis improves, due to the tests' measuring acetoacetic acid and not beta-hydroxybutyrate acid. Positive-Any other color except yellow or clear [73] May be the result of other disease processes. Cornell University-Feline Health Center-Urine Monitoring Flash MovieHow to Read Ketone Test Strips.
A Tozzo Frios conta com uma vasta gama de produtos como: frios, laticA­nios, embutidos, enlatados, congelados e produtos a granel. Toward the bottom of this page is a practice exam, almost the same as what you will see when you come to the campus to take the on-campus exam.
The ear thermometer (on the right) doesn't contact the ear drum, so it is measuring the amount of infrared light emitting from the ear. This digital thermometer measures the room temperature and can take readings of the ear or forehead. The ear and forehead measure the amount of infrared light (heat radiation) coming from the ear drum or the skin. I've seen infrared based thermometers like in the picture used to measure the temperature of a wide variety of items at a distance. The science behind these devices is the use of an LED light and a photodiode (a light detector) that looks at the level of two forms of hemoglobin. Because of the heart beat, the level of hemoglobin in capillaries in the fingers are expanding and contracting with each heart beat. Besides useful for people who have breathing problems, these are being used by pilots and mountain climbers who are at altitudes where oxygen levels are low and monitoring their oxygen saturation would be wise.
When a nurses takes someone's pulse, they pump up the cuff to the point where they can't hear the pulse. The low reading is called the diastolic pressure, which is the pressure when the heart is as rest. You may be surprised that there is a blood pressure cuff that uses an iPhone for the digital readout and storage.
The science behind these modern blood glucose (sugar) meters is to draw in a set amount of blood. I was surprised to see a home test for A1C because I heard doctors describe it as a specialized test.
I couldn't find out exactly how these A1C test strips and meter work, but I imagine it's similar to the way the blood sugar test strips and meter work. Protein in the urine (proteinuria) can indicate a kidney disease or some other serious condition. Ketones in the urine (ketonuria) indicate the body is having trouble using sugar for energy, so it's using fat and proteins instead. Blood in urine (hematuria) gives people some anxiety but isn't always a reason for concern. Another way the density of urine is determined is by measuring how much it bends light (refracts light).
When I worked at the Phoenix Crime lab back in the 70's, the breathalyzer available at that time used a solution of sulfuric acid and a salt called potassium dichromate.
I think the coolest (but not the cheapest) personal medical device is the portable ultrasound imaging machine. What sensor in the left thermometer is responsible for detecting the temperature and name one of its ingredients?
Answer: Percent (%) that hemoglobin is saturated (S) with oxygen (O2) in a peripheral (p) part of the body (for example, fingers).
The below chart is from a urine test strip that measures the concentration of five different substances.
If a person has a high reading for ketones, their urine (and breath) is likely to smell like what? The home pregnancy test will measure the presence of the hormone called human chorionic gonadotropin. Answer: A band at the T region is positive indication of the hormone and therefore indicates the one tested is pregnant. Answer: It means the test is complete and one should then look to see if a band is at the T region. Answer: Cocaine, amphetamine, THC (marijuana), opiates like opium, morphine and heroin, and PCP.
THC is tetrahydrocannabinol, which is the psychoactive chemical in the cannabis plant (marijuana). Unlike the pregnancy test, a band of color showing up at the T region on a drug test indicates what?
Answer: Methamphetamine is the same as amphetamine but methamphetamine has an extra methyl group on it. When ethyl alcohol (ethanol) is completely oxidized (burned) in a fuel cell, 12 electrons are produced as electrical current for each molecule of ethanol.


On the exam, you might be asked to balanced one or two of the compounds in the equation, but not the whole equation. As the alcohol gets converted to acetic acid, the potassium dichromate gets converted to chromium(III) sulfate, Cr2(SO4)3.
The initial color of the solution is yellow.  What is responsible for the yellow color?
After the alcohol is turned into acetic acid, the solution is dark green.  What is responsible for that color? Let's say you were trapped in a mine and you took 1.2 liters of water and did electrolysis on it to get some oxygen, how many grams of oxygen would you get? Which is the most predominant element in water if you base it on its percent of the weight of water?
Which is the most predominant element in water if you base it on its percent of the number of atoms in water? Pregnancy — up to half of women will have glucose in their urine at some point during pregnancy. Diabetes is a lifelong (chronic) disease in which there are high levels of sugar in the blood. Type 1 diabetes can occur at any age, but it is most often diagnosed in children, teens, or young adults.
Gestational diabetes is high blood sugar that develops at any time during pregnancy in a woman who does not have diabetes.
When you find blood or hemoglobin (haemoglobin) during a urine test, further investigation is required to ascertain your true health status. This test is most often performed to detect the kidney disease and you will need to cousult doctor immediately when you discovered large amount of protein shown in the test result.
Some proteins will appear in the urine if the levels of protein in blood become high, even when the kidney is working properly. If the kidney is diseased, protein will appear in the urine even if blood protein levels are normal. If you have Type 1 diabetes, you should always have a supply of the strips used for urine ketone testing and know how to use them. If you have Type 2 diabetes, your doctor or nurse will tell you if you need to do urine ketone testing. If your urine has moderate or large Glucose, Blood, Protein or Ketone present, call your doctor or nurse right away. These are reagent indicator strips that test urine for only ketone (ketostix) or for both ketones and glucose (ketodiastix).
Stix do expire, so check the unopened expiration date when you buy them and record the date you open them. You may test your pet's urine for glucose because you've been instructed to do so by the vet as a method of gauging regulation or your pet is undiagnosed and you want to determine whether there is hyperglycemia. Because of this, it may not be a reliable indicator of what systemic glucose levels are at the time of testing. Ketones evaporate quickly, so there's a chance of getting a false negative test result if you're testing older urine. If you see any color change in the glucose portion of the stix, that means that your pet has exceeded its renal threshold since it last urinated.

My motivation for doing it was partly because I think the average person should take advantage of the tools of science.
That's a good opportunity to monitor health needs at home and to learn more about the science behind these devices and tests.
As electronics got more miniaturized and sophisticated, devices like these have gotten cheaper and common place. Even after she got over the pneumonia, she would often complain about not being able to breath.
A pressure of 126 mmHg meant the person's heart beat had the pressure to raise the mercury in the tube to a height of 126 millimeters (about 5 inches).
The A1C test is a common blood test used to diagnose type 1 and type 2 diabetes and to gauge how well a person has been managing his or her diabetes. The more the inner tube extends above the surface of the urine, the more dense the urine is.
Anti-bodies are proteins created by the immune system to neutralize a foreign bacteria or virus, but also can attach itself to a specific protein. Dark green is after reacting with alcohol, which forms the dark green chromium(III) sulfate. The device is a personal or portable breathalyzer for measuring blood alcohol content in the blood.
Even though it's called the personal ultrasound device, it's marketed more to doctors than the average consumer, but eventually it will be affordable to consumers.
It means that it either adds oxygen atoms or it behaves like oxygen, which is to strip electrons away from things. The reading is the percent of the hemoglobin in red blood cells that are coated with sugar (glucose). Small increases in urine glucose levels after a large meal are not always a cause for concern.
It most often occurs in adulthood, but teens and young adults are now being diagnosed with it because of high obesity rates. Treatment involves medicines, diet, and exercise to control blood sugar and prevent symptoms and problems. Seeing negative urine glucose test, especially repeated negative ones, can mean the pet is approaching hypoglycemia. When you're getting normal bg readings, it means that there are no more ketones being produced. Others catch urine in a dedicated spoon, ladle, or other collection device and dip the stix into the urine. The exam will ask questions about what you learn below plus there will be some questions from the online exam. As the temperature goes up, the electrical resistance comes down and that is converted to a temperature reading on the display.
For this wrist version, you can see the wave which is the changing levels of hemoglobin from which the pulse can be calculated.


Using a blood pressure monitor like the one in the picture could have warned him that his blood pressure was too high despite the medication he was taking. These are often placed on the wrist but not always as accurate as those placed on the upper arm. The glucose in the blood reacts with an enzyme called glucose oxidase that pulls 2 hydrogen atoms off of the glucose molecule.
The science behind it must be like the blood glucose strips and meters, but with an additional enzyme to identify the level of cholesterol.
The computer chip in the devices translate the degrees the light bends into density (specific gravity) of the urine. As the alcohol got converted, the potassium dichromate got converted to chromium(III) sulfate, Cr2(SO4)3. Since people don't breath out hydrogen, then this test uses ethyl alcohol as the fuel to generate electricity.
For information on collecting a urine sample, see clean catch urine specimen. Usually, the health care provider checks for glucose in the urine sample using a dipstick made with a color-sensitive pad. The main purpose of this Glucose Urine Test is use to track the existence and level of Diabetes. When there is not enough insulin present your cells cannot use sugar to obtain the energy they need. Knowing that the pet's blood glucose levels are too low means that you can take action with a sugar source or some food to ward off a possible hypo episode. Note that positive urinary glucose results are not indicative of your pet's blood glucose level at the time it urinated. What you are seeing when you test urine for ketones and the blood glucose is in normal ranges are the "leftovers" of the ketones which were produced by the high bg episode. However, after realizing how unsafe these were, you can't really find these in the stores anymore.
One type of thermocouple is used by your gas water heater or gas oven to sense if the pilot light is on. In the hospital I noticed they used a device called the Pulse Oximeter to measure her pulse and oxygen levels. That might have saved him the devastating effects from the stroke that he still suffers with. The test strip has a reagent (a chemical that reacts with some other chemical) that is specific for acetoacetic acid (a common ketone found in urine). This is the same kind of instrument used to measure the charge of a battery (by measuring sulfuric acid density). Saliva is placed on the bottom indentations, and it travels up the strip to where the letters are. To make that conversion, an oxygen atom is added to the alcohol and a hydrogen atom is removed.
You are then only using what you need when you need it, having the rest still sealed and potent until the indicated expiration date. They will continue to show up in the urine for a while but their concentration will become less and less until they're gone. However, when computers got smaller and less expensive, it was possible to own a computer and take advantage of everything it could do. So the Breathalyzer had a light pass through the solution and the change in the color correlated with the amount of alcohol in the breath.
It cost $200, but was very useful in discovering that her oxygen levels were truly very low.
So we bought one of these automatic blood pressure monitors and checked his blood pressure about 3 times a day.
One problem density can indicate is an imbalance in electrolytes such as potassium and sodium ions. The electron flows down a wire and is measured with an electrical meter which shows up as a reading on the display. To find the amount of alcohol in the blood, the machine multiplied by 2100 because the blood always has 2100 times more alcohol in it compared to the alcohol in the breath.
Be sure to read the colors at those time intervals because the colors will continue to darken and a later reading will be an incorrect result. The metals that are selected to be sandwiched together to make these thermocouples can be chromium, nickel, copper, tungsten, and platinum. This prompted the doctor to prescribe a portable oxygen concentrator that gave her pure oxygen when she needed it. Again specific antibodies for each drug is present in the strip along with a dye attached to the antibody.
The more alcohol present the more electron current will flow, which makes the reading go up. As they are exposed to heat, they generate an electrical voltage, which can be converted to a reading on the display window. Blood cells live for 2 or 3 months, which is why this test gives you an idea of the blood sugar level over the last 2 or 3 months. Apparently the drug attaches to the antibody and dye and creates a group that is not carried along by the urine to the T area. This device is called a fuel cell because it is using alcohol as a fuel to generate electricity. Only if the drug is NOT present does the urine carry the antibody and dye combination to the T area.
In the future, your cellphones will likely run off of drinking alcohol (ethyl alcohol) or methyl alcohol because alcohols can produce a lot more electricity for a longer period. Again, if the antibody-dye combination forms a line at the T area, then that drug was not present.
In other words, your cellphone will stay charged for a month without adding more alcohol to it.
