    Assessing Enzymes & Proteins in Blood

    Alanine Aminotransferase (ALT, or SGPT)

    It is one of the liver enzymes. Cholesterol-lowering medications may raise the levels of this enzyme. It is used to evaluate liver disease or hepatitis

     Target Values:

    5-50 U/L

    Preparation:

    The test could be carried out anytime of the day without fasting.

     

    Aspartate Aminotransferase (AST, or SGOT)

    This is a liver enzyme that’s is found in blood stream following injury or cell death. Increased levels are seen with liver disease, myocardial infarction (MI) and some medications, including cholesterol- lowering medications.

     Target Values:

    7-40 mg/dl

    Preparation:

    The test could be carried out anytime of the day without fasting.

     

     Creatinine

    Illness, kidney disease, muscle injury and some medications cause elevation of creatinine

     Target Values:

    0.7 – 1.4 mg/dl

    Preparation:

    The test could be carried out anytime of the day without fasting.

     

     Creatnine Kinase (CK)

    It is a late marker for detection of heart attack. Other conditions that may cause elvation of this enzyme are liver and kidney disease, pernicious and megaloblastic anemias, malignancy, progressive muscular dystrophy, and pulmonary emboli.

     Target Values:

    100 – 220 U/L

     Preparation:

    The test could be carried out anytime of the day without fasting.

     

    Myoglobin (Mb)

    Myoglobin is a muscular protein that could be elevated with muscle injury or inflammation.

     Target Values:

    30 – 90 μg/ml

    Preparation:

    The test could be carried out anytime of the day without fasting.  Intense exercise before the test could increase the myoglobin levels

     

     Troponin T (cTNT)

    This is a protein that is related to contraction of heart muscle and is a marker for heart muscle damage.

     Target Values:

    0.0 – 0.10 μg/ml
