If a person is taking a blood test to check for cholesterol and triglyceride levels, and that person has been smoking weed with more or less frequecy within the last 2 weeks, will that specific test show this? In other words, will traces of weed stay in your system and show regardless of the blood tests a person takes, or do they have to make a drug test to show this and not just any test?
Drug tests are completely different.
And, according to wikipedia , cannabis is only detectable in the blood for two days.
Don’t be so paranoid 
Nope. FWIW I’m a pretty regular medicinal and recreational smoker and just had a CBC/basic chem panel done last week with textbook perfect results.
If it’s testing you’re ordering for yourself as an adult you have no concerns. If you’re a minor and your parents are requesting the test, they do have the capability to order a drug panel for you without your knowledge or consent. I learned this when I pulled a copy of my chart from my pediatrician and discovered a sheaf of notes about how my parents had contacted her requesting secret random UAs to screen for drug use. It happened three or four times and all came back negative/WNL, which is kind of surprising considering all the drugs I was doing at the time. :smack:
The blood tests that a doctor orders are very specific for what they are testing. The chemistry behind the tests is quite involved, using many different steps often to get the result of the levels of one particular serum chemical (like cholesterol or triglycerides). A lot of effort is put into making sure there isn’t cross-reactivity between other things present in the blood to make the results inaccurate. I am not familiar with any cross-reactions between cannabis and the reagents used to measure cholesterol-triglycerides; if there aren’t any, there would be no effect from having cannabis in your blood. If there are, it would only make your cholesterol-triglycerides readings inaccurate; it wouldn’t come up as “ALERT! ALERT! PRESENCE OF CANNABIS DETECTED!!!”
Hehehe, thanks everybody, much appreciated!
