Hi thank you for reaching out to us.

We understand your concern regarding the reading of the CT value. We will assist you in resolving your issues and concern.

For your information, the cycle treshold (CT) value indicates the number of cycles of a virus. However, we should not rely based on CT value alone and a more detailed history need to be elicited to stratify your risk regarding the disease.

High CT value may indicate:

  • The disease is at the end stage or resolving
  • Infectious rate is low
  • The case screening and rt-PCR is done at the early stage

If you need a second opinion, you may contact and speak to our doctors online via teleconsultation so that we can assist you further and better.

We hope that our answers help. Thank you.
