Euglobulin Lysis Time (ELT)
Use
The euglobulin lysis time is a global nonspecific screen of the fibrinolytic system.
Special Instructions
Not provided.
Limitations
This semiquantitative assay has a wide variation in lysis times among healthy individuals which limits its diagnostic potential. Conditions such as hypofibrinogenemia and factor XIII deficiency can cause shortened lysis times due to decreased fibrin or lack of fiber cross-linking, respectively. Factors like traumatic venipuncture, prolonged stasis, or improper sample preparation can invalidate results.
