| A Reactive result indicates presence of HIV p24 antigen and/or HIV specific antibodies and a supplemental test will follow (HIV-1/2 Antibody Differentiation Supplemental by Qualitative Enzyme Immunoassay (EIA)). A Nonreactive result indicates no HIV p24 antigen or HIV specific antibodies present. Tests of Public Health Significance (TOPHS): All tests submitted to SHL at no charge as Tests of Public Health Significance (TOPHS) must come from State of Iowa Department of Health and Human Services (HHS)-approved test sites, such as Community-Based Screening Services (CBSS) and Integrated Testing Services (ITS) sites. To qualify as TOPHS testing individuals must must meet one or more of the following criteria: 1. Men who have sex with men; 2. Disproportionately impacted populations (as determined by Iowa HHS based on epidemiological data) -- Black/African American, Hispanic/Latino; 3. Persons who have ever injected drugs (PWID); 4. Persons who exchange sex for drugs or money; 5. Persons with an STI diagnosis within the last 12 months or someone who has a partner in another risk group (PWID, MSM, recent STI, exchange sex for drugs or money); or 6. Persons in need of confirmatory testing who have had reactive rapid HIV test results at an Iowa HHS-approved site -- select "Previous related diagnosis/therapy" as an indicated risk. | |||||
