Part Descriptions
LP28491-6 Gamma hydroxybutyrate
Gamma Hydroxybutyrate (4-hydroxybutanoic acid) is both a drug and a naturally occurring substance found in the body. As a drug, it is approved for treatment of a rare form of narcolepsy, but is also being manufactured illegally. GHB is considered a "date rape" drug because it can be mixed with a liquid and given to unsuspecting victims. Peak plasma levels are attained approximately 30 minutes following administration. GHB and its metabolites are often hard to detect as they quickly leave the body.

LP32035-5 Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
