Abstract
|
|
|
|
For the evaluation of our laboratory’s 11-nor-Δ⁹-tetrahydrocannabinol-9-carboxylic acid (THCCOOH) urinalysis test, THCCOOH urinalysis test was carried out with Certified Reference Material (CRM). The used CRM was THCCOOH in freeze-dried urine produced by NIST as Standard Reference Material 1507b. Comparing the estimated value of our laboratory with CRM, the results was coincided in the confidence level of approximately 95%.
