What Affects the Test
Reasons you may not be able to have the test or why the results may not be helpful include:
- Taking large doses of the medicine epinephrine.
- Taking medicines, such as isoniazid for tuberculosis or metformin (Glucophage) for diabetes.
- Using a lot of acetaminophen (such as Tylenol) or alcohol.
- Exercising prior to this test.
- Clenching a fist while the blood sample is being drawn. Also, lactic acid levels may be higher if the tourniquet is around your arm for a long time.
