TS-Auto Automated Coagulation Analyzer

TS-Auto Automated Coagulation Analyzer

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Preoperative Coagulation Screening for Surgical Risk Assessment

• Primary Use: Provides a fully automated, multi-channel coagulation analyzer using dual magnetic bead electromechanical detection technology to perform coagulation screening tests including PT (prothrombin time), APTT (activated partial thromboplastin time), TT (thrombin time), and FIB (fibrinogen), enabling comprehensive assessment of patients prior to elective surgery .

• How it helps: For the anesthesiologist and surgeon, the TS-Auto delivers critical coagulation parameters that identify patients at risk for perioperative bleeding—enabling informed decisions about surgical delay, transfusion planning, or preoperative correction of coagulation defects. For the patient undergoing elective surgery, preoperative coagulation screening detects unsuspected bleeding disorders, vitamin K deficiency, or liver disease, preventing catastrophic intraoperative hemorrhage and reducing postoperative complication rates.

2. Anticoagulant Therapy Monitoring for Warfarin and DOAC Management

• Primary Use: Monitors PT, INR (International Normalized Ratio), and APTT in patients receiving oral anticoagulants including warfarin (Coumadin), direct oral anticoagulants (DOACs), and heparin-based therapies, with built-in INR calculation and reporting .

• How it helps: For the cardiologist and primary care physician, the TS-Auto’s INR measurement capability enables precise warfarin dose titration—maintaining therapeutic INR within the narrow target range (2.0-3.0 for atrial fibrillation, 2.5-3.5 for mechanical heart valves). For the patient with atrial fibrillation, mechanical heart valve, or venous thromboembolism, regular INR monitoring prevents both ischemic stroke (from subtherapeutic anticoagulation) and catastrophic hemorrhage (from supratherapeutic anticoagulation), enabling safe long-term warfarin therapy.

3. Unfractionated Heparin (UFH) and Low Molecular Weight Heparin (LMWH) Monitoring

• Primary Use: APTT monitoring for unfractionated heparin therapy assesses anticoagulation adequacy during acute management of venous thromboembolism, myocardial infarction, and cardiac surgery requiring cardiopulmonary bypass .

• How it helps: For the intensivist and cardiac surgeon, the TS-Auto provides rapid APTT results to titrate intravenous heparin infusions—maintaining therapeutic anticoagulation while preventing bleeding complications. For the patient with acute pulmonary embolism, massive deep vein thrombosis, or during cardiac surgery requiring cardiopulmonary bypass, accurate heparin monitoring prevents life-threatening thrombus extension or devastating intraoperative bleeding.

4. Disseminated Intravascular Coagulation (DIC) Diagnosis and Management

• Primary Use: Performs comprehensive coagulation panel including PT, APTT, TT, and FIB for diagnosis and monitoring of disseminated intravascular coagulation—a life-threatening condition characterized by simultaneous bleeding and thrombosis .

• How it helps: For the intensivist and hematologist, the TS-Auto’s multi-channel simultaneous testing capability enables rapid DIC panel completion, identifying the characteristic coagulation abnormalities (prolonged PT/APTT, low fibrinogen, elevated FDPs) that distinguish DIC from other coagulopathies. For the patient with sepsis, trauma, obstetric complications, or malignancy, early DIC diagnosis enables timely intervention with clotting factor replacement, anticoagulation, and treatment of the underlying cause—reducing mortality from this critical complication.

SECONDARY & SUPPORTIVE USES

1. Liver Disease and Coagulopathy Assessment: Evaluates synthetic liver function via PT and INR prolongation in patients with cirrhosis, hepatitis, acute liver failure, and alcoholic liver disease—where the liver’s inability to produce clotting factors increases bleeding risk .

2. Vitamin K Deficiency Detection: Identifies patients with fat malabsorption syndromes (celiac disease, cystic fibrosis, biliary obstruction), prolonged antibiotic use, or malnutrition who develop vitamin K-dependent factor deficiency (factors II, VII, IX, X) with elevated PT.

3. Factor Deficiency Evaluation: Performs mixing studies and factor assays for coagulation factors II, V, VII, VIII, IX, X, XI, XII to diagnose inherited bleeding disorders including hemophilia A (factor VIII deficiency), hemophilia B (factor IX deficiency), and von Willebrand disease .

4. Protein C and Protein S Deficiency Screening: Detects inherited thrombophilias (hypercoagulable states) including protein C and protein S deficiencies—conditions predisposing patients to recurrent deep vein thrombosis, pulmonary embolism, and pregnancy loss .

5. Lupus Anticoagulant (Antiphospholipid Syndrome) Testing: Performs dilute Russell viper venom time (dRVVT) and mixing studies to detect lupus anticoagulant—an autoantibody causing arterial and venous thrombosis, recurrent pregnancy loss, and thrombocytopenia requiring lifelong anticoagulation .

6. Fibrinogen (Factor I) Deficiency and Dysfibrinogenemia Assessment: Quantifies fibrinogen levels via Clauss method for diagnosis of inherited (afibrinogenemia, hypofibrinogenemia) and acquired (DIC, liver disease) fibrinogen disorders affecting bleeding risk.

7. Heparin Contamination Detection (Surgical Specimen Monitoring): Monitors heparin levels during cardiopulmonary bypass, ECMO, and cardiac catheterization procedures requiring precise anticoagulation control while preventing heparin-induced bleeding.

8. Emergency Department (ED) Rapid Coagulation Panel: Supports rapid turnaround (3-999s test time) for emergency department patients presenting with bleeding, bruising, or thromboembolic symptoms, enabling immediate anticoagulation decisions .

9. Obstetric and Pregnancy Complication Monitoring: Assesses coagulation status in pregnant women with preeclampsia, HELLP syndrome, placental abruption, and antiphospholipid syndrome—conditions associated with DIC and thrombotic risk.

10. Neonatal and Pediatric Coagulation Testing: Provides coagulation testing for neonates and children with suspected hemophilia, vitamin K deficiency bleeding (VKDB), and liver disease using small sample volumes.

11. Post-Thrombosis Anticoagulation Monitoring: Monitors warfarin or DOAC therapy following treatment for DVT, PE, or cerebral venous sinus thrombosis, ensuring adequate secondary prevention while minimizing bleeding risk.

12. Outpatient Anticoagulation Clinic Management: Supports PT/INR monitoring in dedicated anticoagulation clinics for patients on long-term warfarin, with electronic data storage and LIS connectivity for result tracking.

13. Clinical Research and Drug Trials: Provides coagulation endpoint measurement for clinical trials of anticoagulant medications, antiplatelet agents, and hemostatic therapies with QC data storage and Levey-Jennings charting.

14. Quality Control and Laboratory Accreditation: Built-in QC data storage for PT, APTT, TT, FIB with dot chart display supports laboratory quality assurance programs, Westgard rule application, and ISO accreditation .
