What else can I help you with?
How do you calculate false negative?
To calculate the false negative rate, you need to determine the number of false negatives (instances where a positive case is incorrectly classified as negative) and the total number of actual positive cases. The formula is: False Negative Rate = False Negatives / (True Positives + False Negatives). This metric helps in evaluating the performance of a diagnostic test, particularly in contexts where missing a positive case has significant consequences.
When taking a urine test for marijuana and cocaine what else can give a false positive for drugs that will inhibit one from getting a job?
Bezodiazepines, barbiturates, PCP, MDMA, opiates. Any controlled or illegal substance in your urine, lacking a prescription or (in the case of "medical marijuana") a special licence, will cause you to fail a drug test.
Why test positive for mogadon?
Are you asking why you failed a drug test if you're only taking mogadon? If so that's because Mogadon is a benzodiazepine, which all urine analysis drug tests will test for. If your asking why mogadon is in your system without taking it. It could be a false positive in which case you should ask for a more thorough examination of metabolites in your urine. The test center will send it a lab that has a GC/MS machine that is useful in seperating all of the metabolites in your urine by molecular weight. This will tell then test center EXACTLY what is in your system.

Can some cancers cause a false positive pregnancy test?
No. Pregnancy tests are looking for a hormone in your blood and urine that is only present when you are pregnant. Some infertility treatments have this hormone in them and therefore can show up a false positive. Cancer will not. Very occasionally an ovum is fertilised but the embryo does not develop and the placenta grows out of control. This will give a very strong positive on a pregnancy test and has to be dealt with as a matter of urgency. It is called a hydatidiform mole and may (just may) develop into a cancer. Ammendum:After only minor investigation on the subject, I was able to find documented evidence of some cancers (or their subsequent treatments) causing false positive pregnancy tests. One case study published by Tze-Kiong et al, of the Kaohsiung Medical University in Kaohsiung, Taiwan, discussed the clinical history of two female cancer patients. One patient was diagnosed with cervical cancer and the other with colon cancer. Both patients tested positive on urine pregnancy tests (based on the criterion of above-normal HCG urine levels) but otherwise were shown not to be pregnant. The article can be found on MedScape (http://www.medscape.com/viewarticle/556653). Also certain types of ovarian, uterine, and breast cancers have been shown to cause excretion of HCG in the urine. (http://www.justmommies.com/articles/false-positive-pregnancy-test.shtml) Keep in mind that tumors utilize and secrete some of the same growth factors that zygotes and fetuses do considering that both tumors and newly fertilized eggs are characterized by rapid and expansive cell replication.

The question is nonsense, on the surface. Urine test for THC do not provide a score. They do, however indicate the presence or absence of illegal substances. In the case of THC, a positive result (indication of the presence of THC) is potentially bad.
Can anxiety cause a false positive for amphetamine?
If that chemical occurs naturally, I'd think that the test would allow for latitude in that case. So, you probably took a medication that had amphetamine in it.

How could you get a false pregnancy?
A positive pregnancy test is simply a rise in hormones secreted in urine or blood. False positive pregnancy tests are rare but can be caused by adrenal tumors, or possibly certain medications. A false pregnancy test when a woman is actually pregnant means she isn't secreting the hormones in her urine yet, or they are high enough to be picked up by the test she uses. Blood test for pregnancy is more accurate.
What can make a pregnancy test read a false positive?
There are a few factors that can result in a false positive. Most of the time though false positives are rare! I recently experienced this. I have 4 children and have never had a false positive! My test never showed up unless I was pregnant. I recently had 5 tests show a faint positive and went to the doctor for blood test which was negative. I was told that a cyst on your ovaries can sometimes make a test appear positive (false positive). Other factors include chemical pregnancy. This is one where everything develops as though you are pregnant, except for the baby. If you are on any medication that contains the pregnancy hormone (HCG), this also can make your test turn up positive. It is best to have a blood test done by the doctor to totally insure you are not pregnant.
