Widely used anticancer drug acting as an antimetabolite in DNA synthesis.

>2.27 µg/mL (> 5 µmol/L)
Enzyme immunoassay(EIA), Radio immunoassay(RIA), High performance liquid chromatography (HPLC).
Side effects are mostly dose related and include oral ulcers, hair loss, fatigue, headache, stomach upset, nausea, diarrhea and bone marrow suppression. It can also cause liver and kidney disease, lung disease including fibrosis, skin reactions, infections by organisms like Pneumocystis carinii which do not infect healthy individuals, cancer of the lymph system and birth defects in the unborn child. Combination with salicylate increases incidence of toxicity, due to possible reduced excretion by the kidney.
