Viral Tests

How It Is Done

Samples can be collected in several ways.

• A blood sample can be taken from a vein in the arm.
• A tissue sample can be taken directly from the infection, such as a throat swab or skin scraping.
• A sample of stool, urine, or nasal washings may be taken.
• A sample of spinal fluid can be taken through a lumbar puncture (spinal tap).
• A biopsy sample may be taken using a needle or other tool.
