Why the Test is Performed
The test can also be used to monitor patients who are on streptokinase or urokinase therapy for acute MI (heart attack).
A normal value will range from 90 minutes to 6 hours. Euglobulin clot lysis is normally complete within 2 to 4 hours.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What Abnormal Results Mean
A longer-than-normal ELT time may be due to:
A shorter-than-normal ELT time may be due to:
- Blood vessel injury or surgery
- Cancer of the prostate
- Fibrinogen deficiency
- Pregnancy complications (for example, antepartum hemorrhage, hydatidiform mole, amniotic embolism)
- Thrombocytopenia purpura
The test may also be done to diagnose or rule out:
- Spontaneous abortion
- Primary thrombocythemia
- Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
