LOINC description : In general hair analysis provides a longer surveillance window for drug use than other
methods because hair retains drugs longer (weeks or months, compared with days detectable
in blood or urine). Collecting hair specimens is also less invasive than urine or
blood sampling and provides a simple and fast method for detection and quantification
of Risperidone (RSP) and its major metabolite, 9-hydroxyrisperidone (9-OH-RSP). One
study suggests a better relationship between the administered dose and hair concentration
for 9-OH-RSP, than for the parent drug. [PMID: 19595645] Drawbacks for hair analysis
include expense, and environmental contamination of the specimen.;
