Reptilase Time with Reflex to Reptilase Time 1:1 Mix
Also known as: REP
Use
This test assists in diagnosing dysfibrinogenemia or abnormalities with fibrin polymerization. Dysfibrinogenemia is a disorder of abnormal fibrinogen function that can lead to bleeding or thrombotic complications. By measuring the reptilase time, clinicians can understand more about the patient's coagulation status and potential fibrin polymerization issues.
Special Instructions
If Reptilase Time is elevated, then the Reptilase Time 1:1 mix will be added as a reflex test. Additional charges apply for the reflex test. Proper specimen handling and immediate freezing are necessary to maintain sample integrity.
Limitations
Reptilase time measurement may be affected by anticoagulants and certain medications. Incomplete separation of plasma cells can result in inaccurate test results. Hemolyzed or clotted specimens can lead to erroneous readings and must be rejected. The test may not differentiate between different causes of prolonged reptilase time without further diagnostic workup.
