Cryocheck HexLA integrated APTT test for detecting lupus anticoagulant

Evaluation of the Cryocheck HexLA Integrated TCA for the Detection of Lupus Anticoagulant

Observational University Hospital, Strasbourg, France · NCT07313475

This work will test whether the Cryocheck HexLA integrated APTT better detects lupus anticoagulant and is less affected by anticoagulant medications in adults whose blood is sent to the HUS Hematology Laboratory.

What this trial studies

This observational laboratory comparison uses routine blood samples sent to the CHU de Strasbourg Hematology Laboratory for lupus anticoagulant (LA) testing. Samples will be tested with the Cryocheck HexLA integrated APTT and compared to the laboratory's current Cephen LS/Cephen integrated APTT workflow. The analysis will compare sensitivity for detecting LA and the degree to which results are distorted by concurrent anticoagulant therapy. No extra procedures are required beyond the routine diagnostic testing of submitted samples.

Who should consider this trial

Good fit: Adults (≥18 years) whose blood samples are submitted to the HUS Hematology Laboratory for routine lupus anticoagulant testing are eligible.

Not a fit: People who do not have samples sent to the CHU de Strasbourg lab or whose samples lack sufficient volume are not included and will not benefit.

Why it matters

Potential benefit: If Cryocheck HexLA performs better, it could improve detection of lupus anticoagulant and reduce false results, especially in patients taking anticoagulant drugs.

How similar studies have performed: Previous reagent-comparison studies for LA testing have sometimes identified reagents with improved sensitivity, but Cryocheck HexLA itself is relatively new and less widely reported.
