Pass A Saliva & Blood Drug Test

The blood and saliva test are moderately used types of drug tests.

For a saliva test, it's advantage is that it can be done on-site at most workplaces and does not require a laboratory to take and test the sample.

While that sounds like an ideal test for an employer, it's not used more because it causes a lot of false positives and negative readings. It's just not as accurate as other testing methods.

The blood test is not a widely used drug test. It's accurate to test current intoxication levels, but unlike urine or hair testing, it's not very good at looking back over a long time span.
