• swollen lymph nodes.
• patchy hair loss.
• headaches.

Bring the VDRL antigen suspension,controls and samples to room temperature.

Pipette one drop (50 µl) of the test specimen,positive and negative controls onto separate reaction circles of the disposable slide.

Add one drop of well-mixed VDRL antigen next to the test specimen,positive control and negative control.
