Description:
HTLV 1&2 Immunoblot Blood Test (Labcorp)
This test is used to aid in identifying infections with Human T-cell Lymphotropic Virus (HTLV). HTLV is a viral infection that affects t-cells, a type of white blood cell that plays an important role in the body's immune system. An estimated 15-20 million people worldwide are infected with HTLV. There are 2 types of HTLV with type 2 being more prevalent than type 1 in the United States. HTLV is typically spread through sexual contact and exposure to infected blood, especially through intravenous drug use. Infected mothers can spread the infection to their infants during pregnancy or breastfeeding. After infection, HTLV will remain in the body for life. HTLV can lead to the development of serious illnesses including leukemia, lymphoma, chronic pulmonary infection, infectious dermatitis, and other inflammatory disorders. Most HTLV infections are asymptomatic and related illnesses may not develop for months to years after infection.
The immunoblot test for HTLV provides differentiated results for type 1 and 2. For this reason, it is often used to both confirm positive results from an initial HTLV screening as well as determine which form of the virus a person may have.
This test is usually ordered as a follow-up to a positive result from an HTLV Antibody Test. Immunoblot testing is not typically recommended as an initial screening.
Turnaround for this test is typically 4-7 business days.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Detection Period:
The incubation period for HTLV varies from method of contact or exposure.
