Clotting factors including Prothrombin Time (PT)/International Normalised Ratio (INR), Activated Partial Thromboplastin Time (APTT). These assess blood clotting pathways.

Age restriction: Adults 18+ only (guardian consent required for minors).
A Coagulation Screen is a group of tests that evaluate your blood’s ability to clot properly. It detects bleeding or clotting disorders, monitors anticoagulant therapy, or assesses liver function. Your doctor may order this screen before surgery, if you have unexplained bleeding/bruising, or while on medications like warfarin. Swift Blood Tests processes samples rapidly, with results and a doctor’s report typically within a few days.
measures the extrinsic clotting pathway. Prolonged PT/INR can indicate vitamin K deficiency or warfarin effects.
assesses the intrinsic clotting pathway. Abnormal APTT may suggest haemophilia or heparin therapy.
A venous blood sample is required (collected in a blue-top citrate tube). No fasting is typically needed, but avoid certain medications if instructed. Send samples via the next-day laboratory service promptly to avoid delays.
Prolonged times may indicate factor deficiencies or inhibitors.
Adjust doses of warfarin (via INR) or other blood thinners.
Liver diseases impair clotting factor production.
Ensure safe clotting before procedures. The screen categorises haemostatic issues and often leads to specialised follow-up if abnormal.
You may be advised to take a Coagulation Screen if you have any of the following signs or risk factors: Unexplained bleeding: frequent nosebleeds, prolonged cuts, or blood in urine/stool. Bruising easily: large bruises from minor trauma. On blood thinners: monitoring therapy effectiveness and safety. Liver issues or family history of clotting disorders. For example, a patient on warfarin might need regular INR checks to prevent clots or bleeding. Your doctor will interpret results and adjust treatments accordingly.

A Coagulation Screen includes tests like PT/INR and APTT to measure how well your blood clots.

No special preparation usually; inform your provider of any medications.
A small blood sample is taken from a vein in your arm using a needle. It is quick (often under 5 minutes) and routine. You may feel a brief pinch; afterwards, a bandage is applied. There are minimal risks.
Risks are very low. You might experience slight pain or bruising at the needle site, which usually resolves quickly. In rare cases, a small bruise or feeling faint can occur.
Results are typically available within 2–3 working days. Swift Blood Tests provides a detailed doctor’s report explaining your results. You will be notified by email or phone as agreed.
Yes. Swift Blood Tests offers a convenient home sample collection kit (finger-prick or small tube) with instructions, or you can choose a clinic appointment. Follow the included instructions to collect and return the sample by post.
Medications like aspirin or anticoagulants, vitamin K intake, or liver health can influence times.
Prolonged times might indicate bleeding risks; shortened times could suggest clotting risks. Your doctor will explain and recommend actions.
This test is intended for adults (18+). Consult a paediatric specialist for younger patients.
