Protein C
The Stool Ova, Cysts and Parasites (OCP) test is a microscopic examination of a stool sample designed to detect intestinal parasites. This includes identification of parasitic eggs (ova), cysts, trophozoites, and helminths that may infect the gastrointestinal tract. Parasitic infections are a common cause of persistent diarrhoea, abdominal discomfort, bloating, and unexplained gastrointestinal symptoms, particularly following travel or exposure to contaminated food or water. Microscopy remains a valuable diagnostic method for identifying a broad range of intestinal parasites and guiding appropriate treatment.

Clinical Significance
Protein C deficiency may be inherited or acquired. Inherited deficiency is a recognised cause of thrombophilia and may predispose individuals to deep vein thrombosis (DVT), pulmonary embolism, or recurrent clotting episodes. In severe cases, it may present early in life with serious clotting complications. Acquired reductions in Protein C levels may occur in liver disease, vitamin K deficiency, severe infection, disseminated intravascular coagulation (DIC), or during anticoagulant therapy such as warfarin initiation. Because Protein C is synthesised in the liver and dependent on vitamin K, impairment in either pathway can influence circulating levels. Testing is often performed as part of a comprehensive thrombophilia screen, particularly in individuals with unexplained clotting, recurrent miscarriage, or a strong family history of thrombotic disease.
Who Might Benefit From This Test?
This test may be appropriate for individuals who have experienced unexplained venous thrombosis, recurrent clotting events, or thrombotic complications at a young age. It may also be considered in patients with recurrent pregnancy loss where an inherited clotting tendency is suspected. Clinicians frequently request Protein C testing alongside Protein S, antithrombin, and genetic thrombophilia markers to obtain a comprehensive evaluation of clotting risk.
Sample Collection
A blood sample is collected by a trained healthcare professional in a clinical environment. The procedure is quick and minimally invasive. Samples are analysed in accredited laboratories to determine Protein C activity levels accurately.
Understanding Your Results
Results are interpreted within the context of other coagulation markers and clinical history. Reduced Protein C activity may indicate inherited deficiency or an acquired condition affecting clot regulation. Because results can be influenced by acute illness or anticoagulant therapy, timing of testing is carefully considered. Interpretation focuses on overall thrombotic risk rather than isolated numerical values, and further specialist referral may be recommended where abnormalities are identified.
