Test Code TXPRO TOXICOLOGY PROFILE WITH REFLEX TO CONFIRMATION, URINE

Important Note

If it is known that the patient is on a specific medication i.e. amphetamines, benzodiazepines or opiates, please order one or more of the following:

TXAMN If amphetamines are "not detected", the specimen will be sent for quantitative amphetamine determination/confirmation test by GC-MS at an additional charge or order AMUR (as an add-on test if screening is negative).
TXBEN If benzodiazepines are "not detected", the specimen will be sent for quantitative benzodiazepine determination/confirmation test by GC-MS at an additional charge or order BENUR (as an add-on test if screening is negative).
TXOPN If opiates are "not detected", the specimen will be sent for quantitative opiate determination/confirmation test by GC-MS at an additional charge or order OPUR (as an add-on test if screening is negative).

2. This panel does not detect methylphenidate (Concerta, Methylin, Ritalin, Medikinet, Equasym XL). Please order test code METHL (a separate send out test).

3. This panel does not detect certain synthetic opiates. Please order separate tests/panels that contain the specified drug name in the title:

Buprenorphine (Buprenex, Suboxone)
Meperidine (Demerol)
Tapentadol (Nucynta)
Tramadol (Tradol, Ultram, Ultracet)

Useful For

Detecting drugs of abuse. Positive test results are confirmed and/or quantitated at an additional charge.

This test is intended for clinical monitoring and management of patients. It is not intended for non-medical use such as employment or forensic testing.

Specific gravity, pH, creatinine and oxidants will be performed and reported at no additional charge to identify potential adulteration of the urine specimen.
