Laboratory monitoring is widely recommended to measure the anticoagulant effect of unfractionated heparin and to adjust the dose to maintain levels in the target therapeutic range.The most widely used laboratory assay for monitoring unfractionated heparin therapy is the activated partial thromboplastin time (aPTT).nfractionated heparin dose appears to be more important than the aPTT in predicting clinical efficacy. Despite serious limitations, the reliance on the aPTT is likely to continue because of its ready availability and familiarity of clinicians with the test.
Unfractionated heparin as a pharmaceutical is heparin that has not been fractionated to sequester the fraction of molecules with low molecular weight. In contrast, low-molecular-weight heparin has undergone fractionation for the purpose of making its pharmacodynamics more predictable.eparin is usually administered in this form as an anticoagulant. One unit of heparin (the  Howell unit) is an amount approximately equivalent to 0.002 mg of pure heparin, which is the quantity required to keep 1 ml of cat's blood fluid for 24 hours at 0 Â°C.
