Activated Partial Thromboplastin Time (aPTT)
Technoclone aPTT reagents are mixtures of different ratios activators and phospholipids in order to provide reagents with different sensitivities to heparin, lupus and factors
The aPTT Test is used to:
· Screen for congenital or acquired deficiencies in the intrinsic and contact pathways
· Monitor heparin therapy
· Aid in the diagnosis of Lupus Anticoagulants
· Aid in the diagnosis of inhibitors to Factors VIII, IX and XI
aPTT measurement is the time taken for a fibrin clot to form, results are reported in seconds. For monitoring anticoagulant drugs the results are often expressed as a multiple of the mean normal time.
SIRON LIS (Lupus Insensitive)
Liquid low lupus sensitive aPTT reagent containing a soluble activator prepared from ellagic acid.
