Do I need to complete Primary and Backup Testing for all analytes?

Yes, users are required to provide both Primary and Backup Testing information for most analytes. Exceptions:

• Anti-HIV-1/2 rapid tests can be performed using other methods such as Enzyme Immunoassay (EIA) or Polymerase Chain Reaction (PCR) listed on HIV algorithm as backup.
• hCG urine can also use hCG serum method as backup.
