When getting a annual physical does the blood work include a drug test, and does the physical require a urine sample? I'm worried about false positive

When getting a annual physical does the blood work include a drug test, and does the physical require a urine sample? I'm worried about false positive

It does not: You can only be tested for drugs of abuse with your consent. Your physician doing your routine history and physical will not screen you for recreational substances. False-positive drug-of-abuse tests that have medicolegal consequences are very uncommon as the results must be verified by a test using a different chemical principle. And even if you're actually using, your physician is your friend. Read more

Who knows?: Since no one knows what's in those "supplements", there's no way to tell. However, they won't "boost" you testosterone or anything else, other than boosting the $$ out of your wallet and into their pocket. Don't get your medical info from tv or the internet. Avoid the supplements and save your money and your health. Read more

Will drinking Chia seeds in my protein shakes cause a false positive on a drug test?

Will drinking Chia seeds in my protein shakes cause a false positive on a drug test?

Highly doubt it: Chia seeds are very healthy (see https://www. Nlm. Nih. Gov/medlineplus/ency/patientinstructions/000727.htm)
Searching online I saw one report of someone claiming chia seeds caused then to test positive for opiates, and saw that a colleague here states chia can cause positive tests- but she didn't give a reference. I see no other evidence or reason why chia seeds should cause a false positive test. Read more

Can vitamin B2 cause a false positive on a drug test?

Can vitamin B2 cause a false positive on a drug test?

No: I thought this was a strange question, but in researching it found out that this is claimed on some websites. However, I am quite certain that b2 does not cause a false positive on drug tests. It can make your urine bright yellow & some who drink a lot of fluids to dilute their urine before a test will sometimes take b2 so the urine looks yellow rather than clear. Will not cause false positive. Read more

Perhaps a Lexisnexis legal search for case law is more meaningful as legal perception is reality. Read more
