The CT value does not necessarily become a benchmark for the infectious level of Covid-19, this is the explanation!

JAKARTA – Cycle Threshold (CT) value in tes Polymerase Chain Reaction (PCR) often used as a reference for recovering or not someone from Covid-19. Can be done independently, reading CT values ​​must be careful. Recently, messages circulated showing how to read CT values ​​complete with conclusions, such as:

CT 0 – 11 hasil lab invalid
CT 12 – 20 many viruses
CT 21 – 30 healing phase
CT 31 – 40 cured

Summarizing from the Instagram page @dr.fajriaddai, Wednesday (7/7/2021), the Covid-19 Influencer and Volunteer Doctor, dr. Muhamad Fajri Adda’i gave an explanation about this. Doctor Fajri said that the CT value in PCR could not necessarily be a benchmark for healing from Covid-19. Because the symptoms and clinical factors experienced by the patient also need to be considered.

“In fact, the smaller the CT value, the greater the amount of viral genetic material in the patient. The greater the CT value, the less genetic material will be,” explained dr. Fajri in his upload.

However, he also does not deny that a CT value that is too small can mean the test is invalid and must be repeated. However, the lower limit value of the PCR test is different in each tool and reagent used, so it cannot be compared.
