Liver (Definition)

This organ plays a major role in metabolism and has a number of functions in the body, including glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification. It lies below the diaphragm in the abdominal-pelvic region of the abdomen. It produces bile, an alkaline compound which aids in digestion via the emulsification of ...Read more

Not likely: Most drug tests use a first test, TLC or thin layer chromatography, as an initial screen. This test is prone to cross-reaction or "false positive" results for some substances. Usually if the TLC is positive, a second test, gcms or gas chromatography mass spectroscopy is used to confirm. This test is much more specific for specific molecules and not likely to yield false positive results. ...Read more

Which factors that can cause a false positive hepatitis C test?

Which factors that can cause a false positive hepatitis C test?

Autoimmune: No test is perfect. Every test has a false positive and false negative rate. Any condition that leads to lots of antibody production, like autoimmune diseases, can lead to false positive tests. In hcv, antibody response is not as important as viral load since about 25% of people will be truly infected but clear it themselves. Everyone with hcv antibodies needs an hcv RNA test for active infection. ...Read more

Can you tell me if I'm getting tested for hepatitis c/antibodies does it also test for thc?

Can you tell me if I'm getting tested for hepatitis c/antibodies does it also test for thc?

No: Drug-testing is a specific test, usually of urine, and you must be informed that you are being tested in most (if not all) states. The test for hepatitis c antibody is a blood test that is specific for that one problem. If your test is positive, further testing needs to be done to determine the activity and extent of the hepatitis c infection. There is evidence that marijuana may damage liver. ...Read more

How often do false-positive results show up on hepatitis C tests?

How often do false-positive results show up on hepatitis C tests?

Depends: About 25% of people who have positive hcv antibody tests will have negative hcv viral load (RNA) tests. This means they are not chronically infected. Most of the time, this is not a true "false positive" test, because the person spontaneously cleared the infection after true exposure. The antibody test indicates exposure and the hcv RNA test indicates active infection. ...Read more

Male 57, hepatitis C antibody result says reactive 14 with cutoff of 1. Test performed byy ECLIA. How much chance of false positive. Prognosis?

Check viral load: Even when people have high titer hepatitis c antibody responses, some do not have active infection because their immune system cleared their virus on their own. So the first step is to check a hcv viral load (rna). If the virus is detected in the blood then you do have active infection. At that point you need testing to see how much liver scarring (fibrosis) you have. Work with a specialist. ...Read more

It is possible that the antibody result is a false positive. This is unlikely ...Read more

Is there anything in Norco (hydrocodone and acetaminophen) or anything about hepatitis C or liver damages that can cause false cocaine results in a mouth swab test?

Is there anything in Norco (hydrocodone and acetaminophen) or anything about hepatitis C or liver damages that can cause false cocaine results in a mouth swab test?

Not that I know of: Norco (hydrocodone and acetaminophen) is a combination of acetaminophen (which you should be very cautious with if you have hep C) and hydrocodone, and am unaware of any false positives with either drug, or with hep C. Any positive on either a urine or saliva test should be subjected to confirmation, which can tell a false positive from a true one. ...Read more

I am 37 weeks pregnant. I took a home drug test for THC and test positive. What does the state of mo do if I give birth and my baby and I are positive?

I agree: I understand your concerns about legal action. Your child will continue to smoke mj when you do & get even more through breast milk. He'll be far more " stoned" than you because of his size, which will harmfully impact his development. He'll have high risk of accidental injury or death if you parent while "stoned." if you disclose & seek help, you & your baby will both benefit. ...Read more

I took a drug test 5 days ago and came out with my THC levels14% positive, if I take a drug test will it come out with anything?

Yes: If you are positive for thc than you have been exposed to the active ingredient in marijuana, tetrahydrocannabanol. This can occur from smoking the plant, inhaling the smoke from a second hand source or taking a medication like marinol. Do any of these fit your situation? If not see your doctor about re-testing. ...Read more

I took metformin 500 mg and I was wondering how long after stopping that it was out of your system and could it cause a false positive drug test?

I took metformin 500 mg and I was wondering how long after stopping that it was out of your system and could it cause a false positive drug test?

Metformin 500: Metformin 500 is usually taken twice a day - out of your system every 12 hours.

I don't think it can cause a faulse positive test if you are monitoring your blood sugar.

If you think the metformin associated blood glucose values are too high or too low please contact your doctor. ...Read more
