Do I have to take 2 urine tests one is a methadone and the other a drug panel if the dr didn't discuss them to me?
How can I pass blood and urine tests after I took a few puffs of a marijuana cigarette? I have been hired to a new job unexpectedly and I have to take test for health and drugs, help!
Out of luck: If those few puffs were enough to give you a high, it was likely that it would raise your thc to detectable levels (usually 50 ng/ml). If it was truly a "few" puffs, it is likely that you did not achieve significant levels. However, there is nothing you can do now. Water loading will lower your urine's specific gravity and cause a failure of the test. No internet product actually works. ...Read more

Hello.: Hello. The normal specific gravity for an adult ranges from 1.001 to 1.030. This tells you how concentrated your urine is (i.e., are you well hydrated). Yours is fine.

If your menstrual blood was an issue, this would be a contaminant and you would be able to tell because there would be a number of epithelial cells noted on the lab report. ...Read more

Should the urine tests still be performed even though the plasma free metanephrine has been done?
Often no: The plasma has more sensitive and more specific and generally adequate (better) in most situations. It would depend if the doctor is more worried about a false positive (finding pheochromcystoma you really don't have), or more worried about false negative (missing the disease when you really have it). Your doctor would decide based on your symptoms which is the bigger worry /risk. ...Read more
