Part Descriptions
LP18447-0 N-methylhistamine
N-methylhistamine (NHM) is the primary metabolite of histamine, which is produced by mast cells. Mast cells are often activated due to an allergic immune response. Increased production of histamine is seen in patients with severe allergic reactions and in patients with mastocytosis, a rare condition associated with abnormal proliferation of mast cells. NHM levels are measured to screen and monitor patients with such conditions.

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.
