Partial Thromboplastin Time mixing study is done to detect the cause of a prolonged PTT screening test. It is used to distinguish factor deficiencies from factor inhibitors, such as lupus anticoagu...

The peripheral film evaluation is the capstone of a panel of tests called the complete blood count (CBC) or hemogram. Microscopic blood film review is essential whenever instrument analysis indicat...

Protein C is a vitamin-K dependent coagulation inhibitor which regulates the activity of Factor V and factor VIII. Disease caused by Protein C deficiency may be congenital or acquired.

Protein S (S-Protein) is a vitamin K-dependent plasma glycoprotein that is found in two forms in plasma. A Protein S deficiency may be acquired or inherited and is associated with an increased risk...

The prothrombin time (PT) is a useful screening procedure for the extrinsic coagulation mechanism including the common pathway (detects deficiencies in factors II, V, VII, and X). The PT is frequen...

Prothrombin Time Mixing study is done to detect the cause of a prolonged PT screening test. It is used to distinguish factor deficiencies from factor inhibitors.

The reticulocyte is the last immature red blood cell stage. The reticulocyte count is used to assess the erythropoietic activity of the bone marrow.

The Sickle cell test is done to determine if an individual has the sickle cell disease. However, the test does not distinguish sickle cell anemia from sickle cell trait or other Hemoglobin S syndro...
