Understanding Lab Tests for HTLV-II-associated neurological diseases
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Human T-Cell Lymphotropic Virus Type II (HTLV-II) is a retrovirus that can infect immune cells and has been associated with various neurological complications. While HTLV-II is less well-studied than HTLV-I, research suggests it may contribute to certain neurological disorders over time.
Recommended Test
Human T-Cell Lymphotropic Virus I, II (HTLV-I/HTLV-II) Antibodies, Preliminary Test W/ Confirmation
This comprehensive test detects antibodies against both HTLV-I and HTLV-II viruses in the blood. The presence of HTLV-II antibodies indicates an active infection with the virus, which has been associated with various neurological diseases. The test includes confirmation to ensure accurate results and proper differentiation between HTLV-I and HTLV-II.

Diagnosing HTLV-II Infection
Since HTLV-II-associated neurological symptoms can be subtle and develop gradually, they may overlap with other conditions. Definitive diagnosis requires blood testing to detect antibodies against the virus, confirming infection status and enabling appropriate medical monitoring.
Understanding the Test Results
A positive result indicates HTLV-II infection, though not everyone with the virus will develop neurological complications. Regular monitoring and consultation with healthcare providers specializing in viral infections or neurology is important for managing potential health impacts.
