Diagnostic Tests for COVID-19

1. NAAT (Nucleic Acid Amplification Test) is a type of viral diagnostic test for COVID-19. NAATs detect genetic material (nucleic acids). 

NAATs can use many different methods to amplify nucleic acids and detect the virus, including but not limited to: 

  • RT-PCR 

  • Isothermal amplification including

    • NEAR (Nicking Endonuclease Amplification Reaction)​

    • Transcription mediated amplification (TMA)

    • Loop-mediated isothermal amplification (LAMP)

    • Helicase-dependent amplification (HDA)

    • Clustered regularly interspaced short palindromic repeats (CRISPR) 

    • Strand displacement amplification (SDA) 

2. Lateral flow tests (LFT/LFD) ​

3. Antibody (or serology tests) ​

  • IgM antibody test 

Tests that we provide at Samui Home Clinic

1 

RT-PCR

Real time RT-PCR (Reverse transcription polymerase chain reaction)

  • Universally accepted by ALL countries that require a pre-departure test.

​

2

NEAR

NEAR (Nicking Endonuclease Amplification Reaction)

The average turn around time is less than 1 hour 

Countries that accept NEAR test 

  • JAPAN

  • SOUTH KOREA

  • USA

  • TAIWAN

3

Lateral flow test

Qualitative COVID-19 antigen test 

Antigen tests are immunoassays that detect the presence of COVID-19 antigen, which indicates COVID-19 current infection. 

  • Less sensitivity than real time RT-PCR and NAATs

  • Quick results within 15-30 mins 

4

Antibody IgM test 

Antibodies are detected in the blood of people who have been previously infected with COVID-19 or vaccinated against COVID-19.
