Rapid Maximum Amplitude (MA)

General Information

Lab Name: Rapid Maximum Amplitude (MA)
Lab Code: CRTMA
Description: The TEG 6S instrument assesses blood viscoelastic properties using resonance technology, exposing the blood to a fixed vibration frequency range upon adding calcium and exposure to kaolin with tissue factor. The clotting process is accelerated in this test by the addition of high concentration kaolin and tissue factor. The maximum amplitude achieved under these conditions is measured and provides information regarding clot strength.
Synonyms: MA Rapid, Rapid TEG, Rapid TEG6S
