HIV Screening Test (4th Generation) Blood Test

* This is not a home test kit. You will need to visit a local lab for testing.

What Is the Purpose of the 4th Generation HIV Test?

HIV testing is critical, and the earlier you’re tested, the better your chances of effective treatment if you catch the virus in its earliest stages. The 4th generation HIV test is used to detect acute HIV infection four to 12 days earlier than 3rd generation testing. It tests for both HIV antigens and the antibodies your body produces to fight the virus in addition to both HIV-1 and HIV-2 virus types. This 4th gen HIV test gives you a head start in diagnosis and treatment if it turns out you do have HIV.

Human Immunodeficiency Virus 1/O/2 (HIV-1/O/2) Antigen/Antibody (Fourth Generation) (083935)

What Does the HIV Fourth Generation Test Measure?

By measuring your HIV antibodies and antigens, this 4th generation HIV screening test determines if you have the virus.

Who Should Take an HIV 4th Generation Lab Test?

Anyone who is sexually active should get tested for HIV at least once. You’ll want to test more frequently if you practice unsafe sex or have multiple partners. A 4th gen HIV test should also be taken if you have early symptoms associated with HIV, including:

  • Fever
  • Rash
  • Chills
  • Fatigue
  • Diarrhea
  • Sore throat
  • Mouth ulcers
  • Night sweats
  • Swollen lymph nodes
  • Joint and muscle pain

There is a brief period of time after contracting HIV that it is undetectable, so it’s recommended that you take an HIV  4th generation test at least a month after you think you got HIV.
