Operates on IL Coagulation and ELECTRA systems; evaluates extrinsic coagulation pathway; monitors Oral Anticoagulant Therapy (OAT). Clinical laboratory setting; operated by trained laboratory personnel. Output consists of PT (seconds) and Fibrinogen (mg/dL) values; used by clinicians to assess coagulation status and adjust anticoagulant therapy. ## Clinical Evidence Bench testing only. Method comparison studies performed on 180 citrated plasma samples (100 normal, 80 abnormal) across ACL 3000, ACL Futura, and ELECTRA 1400C systems. PT correlation coefficients (r) ranged 0.993-0.996; Fibrinogen correlation coefficients (r) ranged 0.933-0.957. Within-run precision assessed across three levels for PT and two levels for Fibrinogen; PT %CV ranged 0.8-2.5%; Fibrinogen %CV ranged 3.6-9.8%. ## Technological Characteristics High sensitivity thromboplastin reagent; recombinant human tissue factor (RTF) base. Designed for use on IL Coagulation and ELECTRA automated systems. Quantitative diagnostic assay for PT and Fibrinogen. ## Regulatory Identification A prothrombin time test is a device used as a general screening procedure for the detection of possible clotting factor deficiencies in the extrinsic coagulation pathway, which involves the reaction between coagulation factors III and VII, and to monitor patients receiving coumarin therapy (the administration of one of the coumarin anticoagulants in the treatment of venous thrombosis or pulmonary embolism). ## Predicate Devices - Hemoliance® RecombiPlasTin ([K925604](/device/K925604.md)) - IL Test™ PT-Fibrinogen ([K862301](/device/K862301.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
