The concentration of the substance in the sample is measured in micromoles per nanogram per milliliter (um to ng/ml).
Yes. 50 ng/ml is the cutoff for simple test kits (they don't show positive at under that concentration).

ngml are what they measure in drug test. usually if your pushing that much your a pot head
Yes....DALIY SMOKER HIGH!
Not sufficient information. 5 mg would have to be divided by an amount of liquid to calculate ng per ml.
no this person probably just did herion or actually injected crack into their bloodstream right before the test.(about 8oz...) wow that's alot of drugs
First of all, I would NOT mess around with dosages of drugs without being fully informed. From the nature of this question, I take it you are not a trained doctor nor a pharmacist. A miscalculation could lead to death or serious injury. DO NOT TRY TO FIGURE OUT YOUR OWN DOSAGES FOR DRUGS. THIS SHOULD BE DONE ONLY BY A TRAINED MEDICAL DOCTOR!!!To answer the question, or try to... I'm guessing it is actually ng/mL.... which would be nanograms per milliliter. A nanogram is a billionth of a gram, and a milliliter is a thousandth of a liter.If something is listed as ng/mL, that is a concentration, and not an amount. The difference is like saying something is 5% water, and something has 5 grams of water in it. If it is 5% water, you need to know how much total stuff you have to figure out how many grams are actually water. And if you know there are 5 grams of water, you don't know how much other stuff there is...So, you have to know how many milliliters of blood you were added the pseudoephedrine to figure this out. As I said, DON'T DO THIS WITHOUT PROPER TRAINING, WHICH YOU OBVIOUSLY DO NOT HAVE IF YOU ARE ASKING THIS QUESTION HERE!!!
