Quick answer
The Bleeding Time & Clotting Time (BT CT) Test costs ₹120 at Live Line Health Care. A centre-based check that times how long a small skin prick takes to stop bleeding. No fasting is needed. It uses a blood sample and the report is usually ready the same day.
Also known as: BT & CT, BT and CT, Bleeding Time, Clotting Time, Bleeding Time Test, Clotting Time Test, Coagulation Time
What is the BT CT Test?
The BT CT test measures two simple timings. Bleeding time (BT) is how long a tiny skin prick keeps oozing before it stops on its own, and it mainly reflects how well your platelets and small blood vessels respond to injury. Clotting time (CT) is how long blood takes to form a clot, which depends on the clotting proteins in your blood. Doctors often ask for the pair before tooth extractions, minor surgery or other procedures.
This test is done only at a Live Line centre, not through home collection. Bleeding time needs a timed skin prick, with a trained technician watching the site with a stopwatch and blotting it at fixed intervals, so the reading cannot come from a sample sent to the lab. BT CT is an older screening test and can miss mild bleeding disorders. Many doctors now use it alongside, or replace it with, the platelet count, PT/INR and APTT, which look at clotting in more detail. A normal result is reassuring, but it does not rule out every bleeding problem.
What it measures: The time, in minutes, for bleeding from a small skin prick to stop, and the time for blood to clot.
Parameters included (2)
- Bleeding Time (BT)
- Clotting Time (CT)
Why is this test done?
- A routine check before surgery, dental extraction or a biopsy, when the doctor or hospital asks for it
- Looking into easy bruising or bleeding that is hard to explain
- Screening for a possible platelet function problem, along with a platelet count
- A first look at a family history of bleeding disorders, together with more detailed clotting tests
When should you get tested?
- Bruises that appear easily or without injury
- Nosebleeds or bleeding gums that keep returning
- Bleeding that lasts unusually long after a cut or a tooth extraction
- Very heavy periods
- A date set for surgery or a dental procedure, with BT CT on your test list
How to prepare for the BT CT Test
- 1Visit a Live Line centre for this test, as it cannot be done at home. Eat normally beforehand, since no fasting is required.
- 2Tell the technician if you have taken aspirin, clopidogrel, warfarin or painkillers such as ibuprofen in the past 7 to 10 days, as they can prolong the result. Do not stop a prescribed medicine for this test unless your doctor tells you to.
- 3Wear loose sleeves, as the skin prick is usually made on the forearm, fingertip or earlobe.
- 4Allow a little extra time at the centre, because the timing happens while you wait.
BT CT Test normal range
| Parameter | Typical reference range |
|---|---|
| Bleeding time (BT) | 2–7 minutesIvy method; the Duke method is usually 1–5 minutes |
| Clotting time (CT) | 4–10 minutesvaries with the method used |
Both timings depend heavily on the method and technique, so read your result against the range printed on your own report. Ranges are typical adult values and vary between labs, age and sex. Always use the range printed on your report and discuss results with your doctor.
Understanding your results
- A prolonged bleeding time can point to a low platelet count, platelets that are not working well, von Willebrand disease, or the effect of aspirin-type medicines.
- A prolonged clotting time usually means a marked shortage of clotting factors, as in haemophilia or severe liver disease, or the effect of blood thinners such as heparin.
- A normal CT does not rule out a clotting disorder, since the test picks up only large shortages. If your history suggests a bleeding tendency, PT/INR and APTT are more sensitive.
- A prolonged result usually leads to a repeat and to more detailed tests before any surgery goes ahead. Your doctor or surgeon will decide what is needed.
- Bleeding that does not stop with firm pressure, black stools or vomiting blood need emergency care, not a test booking.
BT CT Test – FAQs
What is the price of the BT CT Test?
The Bleeding Time & Clotting Time (BT CT) Test costs ₹120 at Live Line Health Care, at all 45 centres.
Why can BT CT not be done with home sample collection?
Bleeding time is a live measurement. A technician makes a small prick, starts a stopwatch and blots the site at fixed intervals until the bleeding stops. That cannot be worked out from a tube of blood and needs controlled conditions, so we do this test only at a Live Line centre.
What is the difference between bleeding time and clotting time?
Bleeding time looks at the first stage of stopping a bleed, when small vessels tighten and platelets plug the wound. Clotting time looks at the later stage, when clotting proteins turn blood into a firm clot. One can be abnormal while the other is normal, which helps doctors narrow down the cause.
Is BT CT better than PT/INR and APTT?
No, they do different jobs. BT CT is a quick, simple screen, while PT/INR and APTT are laboratory tests that examine the clotting pathways more closely and can pick up milder problems. For a suspected bleeding disorder or before major surgery, doctors usually prefer these tests along with a platelet count.
Will the skin prick hurt or leave a mark?
You will feel a quick, sharp prick, and the site may ooze for a few minutes, as that is what is being timed. A small mark can stay for some days and usually fades. Tell the technician if you tend to form raised scars or feel faint around blood.
Should I stop aspirin before the BT CT test?
Do not stop it on your own. Aspirin can prolong bleeding time for a week or more, but stopping it can be risky if you have heart disease or a stent. Tell the doctor who ordered the test and follow their advice, and let the technician know the date of your last dose.
Is BT CT needed before a tooth extraction?
Many dentists ask for it, especially if you have a history of bleeding, liver disease or take blood thinners. Some prefer a platelet count with PT/INR instead. Carry the note from your dentist to the centre so that the right test is done before your appointment.
Where can I get the BT CT Test done?
At any of our 45 Live Line Health Care centres in 40 cities across Andhra Pradesh and Telangana, including Hyderabad, Visakhapatnam, Warangal, Kakinada and Nellore. This test is done at a centre, not at home.
