Maxim's FDA Approved HIV-1 Urine EIA test is an enzyme immunoassay for the in-vitro detection of antibodies to Human Immunodeficiency Virus Type 1 (HIV-1) in urine. The test is intended for use in professional laboratory settings as an aid in clinical diagnosis of HIV infection. Before a determination of HIV-1 status can be made, specimens that are repeatedly reactive using this test should be further tested using Maxim's additional, more specific FDA approved Cambridge Biotech Western Blot Kit.
