Testing monitors the levels of antimicrobial drugs, including a spectrum of antibacterial, antimycobacterial, antifungal, antiviral, and antiretroviral therapeutics. Focus Technologies offers testing for voriconazole, an antifungal that requires careful monitoring in certain patients. Testing is performed primarily by high-performance liquid chromatography or bioassay, depending on the type of drug and activity. Most assays can be performed on cerebrospinal fluid or other body fluids, in addition to serum and plasma.
