Coagulation
12 markers in this category
Antithrombin III (Activity)
Antithrombin III Activity assesses your natural anticoagulant system. For older adults, thrombosis risk increases with age, making this assessment important for proactive clotting risk management.
Antithrombin III (Concentration)
Antithrombin III Concentration, paired with activity testing, provides complete anticoagulant assessment for older adults managing thrombotic risk.
D-Dimer
D-Dimer testing helps assess clotting activity. For older adults, D-Dimer naturally increases with age, and age-adjusted reference ranges provide more accurate interpretation.
Factor V Leiden
Factor V Leiden testing identifies the most common genetic cause of increased clotting. For older adults, knowing your genetic status helps contextualise age-related thrombotic risk.
Fibrinogen
Fibrinogen serves as both a clotting factor and cardiovascular risk marker. For older adults, monitoring fibrinogen supports comprehensive cardiovascular and coagulation assessment.
INR
INR monitoring is especially important for older adults, who are more commonly on anticoagulant therapy and more sensitive to warfarin dose changes.
Lupus Anticoagulant
Lupus anticoagulant testing screens for antiphospholipid antibodies. For older adults, identifying this risk factor is important for stroke and thrombosis prevention.
PT (Prothrombin Time)
Prothrombin Time is important for coagulation and liver assessment in older adults, particularly those on anticoagulant therapy.
Protein C (Activity)
Protein C Activity testing assesses a key natural anticoagulant. For older adults, acquired deficiency from liver disease or medications can compound age-related thrombotic risk.
Protein S (Activity)
Protein S Activity is important for thrombosis risk assessment in older adults. Age-related conditions and medications can lower Protein S.
Thrombin Time
Thrombin Time evaluates the final clotting step. For older adults on multiple medications, TT helps identify heparin effect and fibrinogen dysfunction.
aPTT
aPTT is a fundamental coagulation screening test. For older adults on anticoagulant medications or facing surgery, aPTT monitoring helps ensure safe clotting function.
