Description
Number of Tests Included:
Two assessments:
Bleeding Time (BT)
Clotting Time (CT)
What is a CT & BT Test?
A simple test to evaluate how effectively the blood forms clots and stops bleeding. BT checks platelet function, while CT checks clotting factor activity.
Purpose of the Test:
Detect bleeding disorders
Evaluate platelet function
Pre-surgical screening (sometimes)
Assess unexplained bruising or bleeding
Monitor individuals on antiplatelet medications
Detect hereditary bleeding disorders
Who Should Get This Test?
Individuals with frequent nosebleeds or gum bleeding
People with prolonged bleeding after cuts
Patients with suspected clotting disorders
Before surgeries in some cases
People with unusual bruising or petechiae
Components of the Test:
Bleeding Time (BT) – time taken for bleeding to stop
Clotting Time (CT) – time taken for blood to clot
Understanding the Test Report:
Normal Ranges (may vary by lab):
BT: 1–7 minutes
CT: 3–10 minutes
Prolonged BT:
Platelet dysfunction
Low platelet count
Aspirin or blood-thinning medications
Von Willebrand disease
Prolonged CT:
Clotting factor deficiency
Hemophilia
Liver disease
Vitamin K deficiency
Preparation and Procedure:
Routine blood sample (for CT)
Small skin puncture (for BT)
No special preparation required
How is the Test Done?
BT: A small cut is made on the forearm, and time is measured until bleeding stops.
CT: Blood is collected in a capillary tube or vial to measure clot formation time.
Best Time for Test:
Anytime as advised.
Booking and Checking Reports:
You can book the CT & BT test through SDL, arrange home blood sample collection (for CT), and access your reports digitally.
