Undetectable: What It Means

  • “Undetectable” means HIV levels in the blood are so low that standard lab tests can’t find them.
  • With consistent treatment, HIV is suppressed and the immune system stays strong.
  • People who are undetectable do not transmit HIV through sex (U=U: Undetectable = Untransmittable).
  • Regular viral load testing confirms that you remain undetectable.
  • Achieving undetectable status is the main goal of HIV treatment—helping you stay healthy and live fully.
