Things Tested to Detect
Counter Measures
Laboratories know how easy it is to tamper with urine samples and alter the
results. Labs often test to nd out if the sample is legitimate.
Color
If a urine sample looks clear, the lab will suspect that it is watered down.
They cannot report it as positive, but they may reject the sample and inform
your employer that you tried to beat the test. If this happens, the sample
might as well be positive, because you won't get hired. Take vitamin B
complex to color your urine yellow.
Temperature
Urine should be between 91 and 97 degrees. NIDA certi ed labs will verify
temperature. If the sample is out of the accepted temperature range, they
will suspect you added water to the cup, or used substitution. Disposable
pocket hand warmers (sold in department stores) will keep a urine sample
warm, provided that the urine is in a condom or douche bag.
Creatinine
Creatinine is a substance produced by vertebrates, and it shows up in urine.
If
someone substitutes their urine with something other than urine, like Moun-
tain Dew, they will test negative for drugs. However the testee will most
likely not get away with it because Mountain Dew contains zero creatinine,
and labs test creatinine levels to ensure that the sample is valid. Creatinine
levels drop below normal when people dilute their urine. This tests to ensure
that the subject did not drink unusual amounts of water. An *accurate* cre-
atinine "clearance" test would require a urine and blood test 24
hours before
the drug test to determine the normal creatinine level for that individual.
This is almost never done. You should still be cautious because they do of-
ten use the inaccurate method of comparing your creatinine level during the
drug test to an average. People who are drug-free sometimes lose their jobs
for having too low of a creatinine level.
How to Increase Creatinine Levels
Eating foods rich in protein like red meat will slightly increase creatinine
levels. There is no signi cant variation between vegatarians and armavors,
so the e ect protein has is little. Sexual activity also raises creatinine
levels.
I doubt sexual activity in uences creatinine level with much signi cance.
However, a vegetarian that does not have much sex should be concerned.
pH
pH is often changed when people spike their sample with household products.
Use caution when doping urine, pH is usually tested.
6.5 Speci c Gravity
An unusual speci c gravity indicates that a sample has been tampered with.
Age
Age can not be tested using urine. There is a rumor that approximate age
can be detected in urine, and is tested in medical insurance exams. It's a
myth.
Gender
Gender cannot be tested either. As with age, there is a rumor that gender
can be detected in urine, and is tested in medical insurance exams. This is
another myth. It may be argued that a pregnancy test can be used to detect
the gender of the urine provider, but the same test is used to detect prostate
cancer in males.
