There are five commonly used
approaches for drug testing. Using urine sample
is the most widespread method for drug testing.
Urine testing can also produce quicker results
and it is the most inexpensive method of drug
testing.
Getting saliva sample is another alternative of
testing for drugs. Saliva drug testing is not a
common practice for drug tests. The reason is
saliva testing is expensive and a bit inaccurate
in getting results.
Blood test is also used for drug testing and the
most expensive and invasive method. This is
especially required to especially get drug test
results. Drug testing using blood sample is also
very complicated to tamper with.
A new method and very unconventional drug
testing approach is having hair samples. Hair
drug testings with their roots intact will be
submitted to the laboratory by persons
undergoing drug tests. This is also expensive
but relatively more accurate than saliva drug
testing.
Sweat patch tests are also being practiced today
by some drug testing center. This method is very
controversial because some experts believe that
sweat tests are very unreliable. Contamination
is also common with sweat patch test thus
generating false reading. Drug testing using
sweat patches are expensive and very uncommon. The most powerful
drug testing is panel drug testing. Before buy
panel drug testing you need read prescription.
