We report the identification of acetone (0.45mg/mL) and isopropanol (0.17 mg/mL) but without the presence of ethanolin a blood sample from a man suspected of driving under the influenceof alcohol. A preliminary breath screening test with an electrochemicalinstrument (Alcolmeter S-L2) was positive and an evidential breath-testwith a dual wavelength infrared analyzer (Intoxilyzer 5000), recognizedthe presence of an interferant in the subject's breath. The manadmitted drinking moderate amounts of alcohol (vodka) the previousevening and was being treated by his doctor for hyperglycemia byspecial dietary control. This case scenario provides a good example ofsevere metabolic ketoacidosis in an ostensibly healthy man driving on the highway. Biotransformation of the abnormally high concentration ofblood-acetone to isopropanol occurs through the alcohol dehydrogenasepathway.

Another reference (more recent) is even more interesting as it relates to to a person on a low carb high fat diet (like Atkins).

A 59-year-old man undergoing weight loss with verylow calorie diets (VLCD) attempted to drive a car, which was fittedwith an alcohol ignition interlock device, but the vehicle failed tostart. Because the man was a teetotaller, he was surprised and upset bythis result. VLCD treatment leads to ketonemia with high concentrationsof acetone, acetoacetate and beta-hydroxybutyrate in the blood. Theinterlock device determines alcohol (ethanol) in breath byelectrochemical oxidation, but acetone does not undergo oxidation withthis detector. However, under certain circumstances acetone is reducedin the body to isopropanol by hepatic alcohol dehydrogenase (ADH). Theignition interlock device responds to other alcohols (e.g. methanol,n-propanol and isopropanol), which therefore explains thefalse-positive result. This 'side effect' of ketogenic diets needsfurther discussion by authorities when people engaged insafety-sensitive work (e.g. bus drivers and airline pilots) submit torandom breath-alcohol tests.

Not likely. Ethanol in blood tests is usually determined enzymatically, with alcohol dehydrogenase. Interference from other alcohol type or ketones is usually considered to be less than 1%.
No. A low level of iron increases the propensity for the development of iron-deficiency anemia, however.
Tests from a breathalyzer are actually considered to be very inaccurate. They can vary up to 15% from an actual blood alcohol level and have even found to give a false 23% reading of having excessive alcohol levels in a breath when in reality the person doesn't.
In diabetes there is improper metabolism that results in acetone. Acetone can confuse the Breathalyzer, since it give results as ethanol (alcohol).
I saw an episode of Mythbusters where they tried to beat the breathalyzer using tactics rumored to lower the reading. The results of their tests showed that none of the products worked except one (of which I can't remember the name). It actually made the breathalyzer read that the person had an incredibly dangerous amount alcohol in their blood. They did not try medication, but it is safe to say that there is no way to reduce breathalyzer results if you have had too much to drink.
The accuracy of the results may be affected if the patient moves during imaging, has had other recent nuclear scans, or has an irregular heartbeat.
No it doesn't appear that it does from any research on the Internet.
Not unless they were soaked in alcohol.
Pregnancy and hemophilia are two main reasons that these tests are inaccurate.
No. It's just steel or plastic in your mouth.
Until the results of the toxicology lab results or breathalyzer come back.
But some benign diseases and certain cancer treatments may produce an elevated CEA test. Cigarette smoking will also cause the CEA level to be abnormally high.
It is very safe to buy a breathalyzer if it doesn't have any side effects from use. It is safe, but for best results you should purchase new. A used one could be damaged.
The first must be inaccurate because you are sure the second results are correct.
It is important for scientists to communicate their results accurately so that they can be used. Other scientists use this information for their own research.Accuracy in reported experimental results is critical for many reasons:1. Unless the reported results are accurate, other scientists may be unable repeat the experiment successfully.2. Inaccurate results could result in bad decisions being made based on incorrect data.3. Inaccurate results could throw off the results of other experiments that rely on that data.4. In some cases, inaccurate results could end up being dangerous, resulting in an explosion or poisoning.
Other than WHICH errors!
it will lead to inaccurate results
Cultural and language differences in the test subject may affect test performance and may result in inaccurate MMPI results.
The results will be inaccurate.
scientists cannot go deep into the mantle therefore their results would be inaccurate
Because such laboratories have unadapted and out of date techniques to work with. Moreover, there is lack of modern instruments to achieve good results.
At this time there has been no connection between elevated CPK results and Fibromyalgia. Abnormal CPK results may be indicitive of a number of conditions, including: inflammation of the muscle of the heart, heart attack, stroke, inflammation of the skeletal muscles, muscular dystrophy, death of muscular tissue, convulsions, and hypothyroidism.
yes dehydration results in falsely increase in hematocrite level.
Why is the adversary system of law a necessity to produce just results?
