Our Technoclone aPTT reagents are scientifically formulated mixtures featuring precise ratios of activators and phospholipids. This diversity allows us to provide specific reagents with distinct sensitivities tailored to heparin, lupus anticoagulants, and extrinsic factors.

Clinical Utility
The aPTT test is a versatile diagnostic tool used primarily for:
1. Screening for congenital or acquired deficiencies in the intrinsic and contact pathways.
2. Monitoring the efficacy of heparin therapy.
3. Assisting in the diagnosis of Lupus Anticoagulants.
4. Aiding in the diagnosis of inhibitors to Factors VIII, IX, XI, and XII.

Measurement Principles
The aPTT measurement reflects the time required to form a fibrin clot via the intrinsic clotting pathway. Results are reported in seconds or ratio. For monitoring anticoagulant drugs, results are often expressed as a multiple of the mean normal time.
