Infectious disease testing uses a blood sample to look for signs that your body is fighting an infection or has been exposed to one. It may be ordered when you have symptoms, after possible exposure, or as part of routine screening.

What it measures

  • Antibodies — Proteins your immune system makes in response to a specific germ.
  • Antigens — Pieces of a germ itself, which can show up before antibodies form.
  • Nucleic acid (PCR) — Genetic material from a germ, used to detect active infection.
  • White blood cell count — A general marker that can rise or fall with infection.
  • Inflammatory markers — Substances such as CRP that can increase when the body is inflamed.

Who it is for

A clinician may order this test if you have symptoms, had possible exposure, or need screening before a procedure or travel. It is also used to monitor certain ongoing conditions.

Preparation

Most infectious disease blood tests need no fasting. Tell the lab about any medications or recent illness, and follow any timing instructions your clinician gives.

Results and what they mean

Results are reported as positive, negative, or a numeric value, depending on the test. A clinician interprets them alongside your symptoms and history. This is general information, not medical advice; discuss your results with a qualified professional.
