Dr Noor Hisham said the RTK-Ag is used when the turnaround time for the Real-Time Reverse Transcription Polymerase Chain Reaction (RT PCR) technique is more than 48 to 72 hours or if the RT PCR test is not available.Recently, Prime Minister Tan Sri Muhyiddin Yassin was reported as saying that Malaysia was one of the first few countries in the world to use RTK-Ag as Covid-19 screening test and the Health Ministry had been using it since June last year.
The kit was evaluated by the National Public Health Laboratory (NPHL) and the Institute of Medical Research (IMR) to ensure compliance with the standards required and later approved by the Medical Device Authority (MDA) for wider use in the community. headtopics.com
Muhyiddin said the RTK-Ag test was used as a confirmatory test in Sabah since Oct 5 last year and until Jan 14, adding that a total of 365,740 RTK-Ag tests had been conducted with a positivity rate of 3.75% which facilitated the Health Ministry in managing the outbreak in the state.
