PCP
Drug Testing
by Erowid
SUMMARY #
U.S. DRUG TESTING SUMMARY
PCP
Tested for in Standard Drug Tests?
YES
Tested for in Extended Drug Tests?
YES
Possible to Test for?
YES
Detection Period in Urine
3-7 days (single use)
Detection Period in Urine
up to 30 days (regular use)


TEST TYPES #
Urine Testing
10% of PCP is excreted unchanged in the urine. The remainder is metabolized into hydroxylate or glucuronide. Standard urine screening and gc/ms test for both PCP and its metabolites. PCP is stored by the body in fatty lipid tissue for up to several weeks. Chronic users and individuals with high body fat count are at the greatest risk of long-term detection.

Hair Testing
PCP is detectable with hair tests and is included in the standard set of substances tested for by many companies. Hair tests generally take the most recent 1.5 inches of growth and use those for testing. That provides a detection period of approximately 90 days. If an individual's hair is shorter than 1.5 inches, this detection period will be shorter.

Blood Testing
PCP is detectable in the blood for approximately 1-3 days after use.

FALSE POSITIVES #
Substances or Conditions which can cause false positives
In Urine Tests: venlafaxine (Effexor); dextromethorphan; ketamine; MDPV

One article reports that MDPV caused false positives for phencyclidine (PCP). See Macher AM, Penders TM. 2012.
CAUTION & DISCLAIMER #
Erowid's drug testing information is a summary of data gathered from site visitors, journal articles, websites, and other resources. Detection periods depend on amount and frequency of use, metabolic rate, body mass, age, overall health, drug tolerance, and urine pH of each individual. Many substances that are not tested for in basic or extended urinalysis tests CAN be tested for by a laboratory willing to go to the trouble, although that is uncommon.
