"15ng" likely means 15 nanograms, which is a unit of measurement for mass or weight. It represents a very small amount, as one nanogram is equal to one billionth of a gram.
Testing Truths says, "Currently, 50 nanograms of THC metabolites per millimeter of urine defines a "presumptive positive" by NIDA certified labs. These cutoffs are not mandated for all testing facilities. The lab your sample is sent to may use a cutoff level of anywhere from 50Ng/ml to 15Ng/ml for confirmation testing, The fact is, methodology, accuracy and cutoff levels vary from lab to lab. This makes it extremely difficult to take appropriate counter-measures."Source: http://www.passitkit.com/testing1.htm
No, dependent means to rely on or be influenced by something else. It does not mean to replace.
92.5 percent pure silver. MO stands for Modena Italy
If the chlorine test turns orange, it may indicate a low chlorine level in the water. This could mean that the water is not well sanitized and may not be safe for swimming or other uses that require proper disinfection. It's important to address this issue by adding more chlorine to bring the levels up to the appropriate range.
A composed mean is a statistical method that combines the means of subgroups to obtain an overall mean for a larger group. This technique is often used when data is collected from multiple subgroups and an overall average is needed.
No. The military's thresholds are 50ng/ml screening and 15ng/ml confirmation.
It depends on what kind of urine test they will be doing. An instant test panel has a 50ng cut-off and a lab test (gc/ms) is 15ng.
THC (weed) concentration for:Lab (IMMUNOASSAY) , instant drug test - 50ng/mlLab confirmation test(GC/MS or LC/MS/MS)- 15ng/ml
You fail for marijuana if you have more than 50ng/ml in your system ..... Initial Test (IMMUNOASSAY) - 50ng/ml Confirmation test (usually GC/MS or LC/MS/MS) - 15ng/ml ......
Doom: " Yes you will pass .But if the test result of the immunoassay (50ng/ml) are positive then another aliquot of the sample is used to confirm the findings by GC-MS (15ng/ml) "
It all depends on your metabolism and usage. You can buy a self test kit and check it out. I think you can buy them at the pharmacy. Just a small note, if you are going to be tested, know that there are two kinds of urine tests, instant & lab and their cut-offs are not the same. For an instant test, the cut-off is 50ng, but for the lab it is 15ng. So Just because you pass a instant test, doesn't mean you would pass a lab test.
THC(tetrahydrocannabinol) at 50ng/ml"?Source: Erowid?Home drug test and Lab Initial Test (IMMUNOASSAY)- 50 ng/mlLab Confirming Test (GC / MS)- 15ng/mlBut military and some Lab -30ng/ml or less
6633N SAP 10-50 GC/MS is a Quest Labs designation for a standard urinalysis which tests for cannabinoids, amphetamines, opiates etc. There is a 50ng/ml drug/metabolite cutoff level for the initial immunoassay screening with a 15ng/ml confirmation cutoff using Gas Chromotography/Mass Spectrometry (GC/MS) method. Only specimens which fail the initial immunoassay screening, referred to as "presumptive positives", are sent for GC/MS confirmation at the more sensitive level. During the initial immunoassay screening, tests for validity such as specific gravity, creatinine level, alduterant (additive) checks etc. nare performed to ensure that the specimen has not been tampered with and is actual human urine. If a specimen passes intitial screening a "pass" is reported and no further testing is performed.

It mean what you don't what does it mean.
Mean is the average.
It means you smoke a LOT of weed. Getting a result in nanograms per milliliter means they put your urine in a testing machine. First they put the urine in an EMIT or ELISA system. This tech just looks for cannabinoid metabolites in your urine, so 517ng/ml means you smoke quite a bit of pot--the machine won't even show you as positive until you break 50ng/ml, so you're ten times the minimum. The next test if you flunk EMIT is GC/MS. This machine can segregate metabolites, so they look for one specific one--the metabolite for delta-9-THC. Therefore, the cutoff is quite a bit lower--if you've got more than 15ng/ml of delta-9-THC in your sample you fail. If you have 517ng/ml of delta-9-THC in your sample marijuana isn't your problem; dying from smoke inhalation is.
