The HTLV Type 1&2 Antibody Test checks your blood for antibodies against human T-cell lymphotropic virus types 1 and 2. It is ordered when a healthcare provider wants to see if you have been exposed to these viruses, which can affect the immune system.
What it measures
- HTLV-1 antibodies — Proteins your body makes if you have been infected with HTLV-1.
- HTLV-2 antibodies — Proteins your body makes if you have been infected with HTLV-2.
- Reactive or nonreactive result — A screening result that shows whether antibodies were found.
- Confirmatory test result — A follow-up test used when the screening result is reactive.
Who it is for
A healthcare provider may order this test if you have symptoms that could be linked to HTLV, or if you have risk factors such as a history of blood transfusion, injection drug use, or being from an area where the virus is more common.
Preparation
No fasting or special preparation is needed. Tell your provider about any medications or health conditions before the blood draw.
Results and what they mean
Results are usually reported as nonreactive (no antibodies found) or reactive (antibodies found). A reactive result does not mean you have a disease; a clinician will interpret it and may order more tests. This is general information, not medical advice.
