IMA(Ischemia Modified albumin)

IMA (Ischemia Modified Albumin) is a biomarker in the blood used for diagnosing ischemic conditions such as myocardial ischemia (a state where the heart muscle does not receive sufficient blood flow).

Feature

■ Early rise in acute coronary syndrome (ACS)
■ Primary screening test to determine whether to provide intensive observation and emergency treatment for patients who visit with chest pain and symptoms suspected of ACS
■ In the early diagnosis of ACS, IMA has a high sensitivity of 82%.
■ When diagnosing ACS, sensitivity increases to 95% when ECG, cTn, and IMA are used together
■ Elevated within minutes after ischemia occurs

(CK-MB, Troponin T/I are detected 4-6 hours after myocardial damage)

Measurement Conditions

■ Test Procedure for Analyzers (Hitachi 7180)

      - Assay Mode: 2 Point End 16-34

      - Wave length(main/sub): 505/700nm

■ Open reagent

Measurement

Performance

■ Linearity: Correlation coefficient R2 ≥0.990 at 20–100 mg/L

■ Correlation: y=0.9958x + 0.7786 (R2=0.937, n=100, Range=21~98 U/mL)

■ Normal reference value: Serum ≤ 85.0 U/mL (37℃)
