Know more about this test

The Lupus Anticoagulant (LAC) Profile is a group of blood tests that help evaluate the risk of abnormal blood clotting due to the presence of lupus anticoagulant antibodies. It includes DRVVT screen, APTT, and lupus anticoagulant tests to assess clotting times and detect autoimmune activity. This profile is available in Gurgaon with Tata 1mg labs at an affordable price

Doctors may recommend this profile if symptoms include unexplained blood clots, frequent miscarriages, stroke at a young age, or prolonged clotting time on routine lab tests. It is also advised in cases of autoimmune diseases like lupus, or during evaluation for clotting disorders, before surgery or pregnancy.

The profile includes three main tests: dilute Russell viper venom time (DRVVT) to screen for clotting delays, activated partial thromboplastin time (APTT) to measure how long blood takes to clot, and the lupus anticoagulant confirmatory test to detect these specific antibodies.

An overnight fast is preferred but not mandatory for the Lupus Anticoagulant (LAC) Profile. A duly filled coagulation requisition form (Annexure - CR/05) is mandatory for sample collection. Kindly provide complete clinical details and medication history or a doctor's prescription; this information is important for correlation of the test results.

Understanding Lupus Anticoagulant (LAC) Profile

The lupus anticoagulant (LAC) profile is a group of blood tests used to detect lupus anticoagulant antibodies, which are abnormal immune proteins that interfere with the body’s natural clotting process. These antibodies do not cause bleeding; instead, they increase the risk of abnormal blood clots (thrombosis) in veins and arteries. This test helps diagnose antiphospholipid syndrome (APS), a serious autoimmune condition linked to complications like deep vein thrombosis (DVT), stroke, repeated miscarriages, and pregnancy-related issues.

Doctors may recommend this profile if symptoms include unexplained blood clots, frequent miscarriages, stroke at a young age, or prolonged clotting time on routine lab tests. It is also advised in cases of autoimmune diseases like lupus, or during evaluation for clotting disorders, before surgery, or during pregnancy.

The profile includes three main tests: dilute Russell viper venom time (DRVVT) to screen for clotting delays, activated partial thromboplastin time (APTT) to measure how long blood takes to clot, and the lupus anticoagulant confirmatory test to detect these specific antibodies.

An overnight fast is preferred but not mandatory for the Lupus Anticoagulant (LAC) Profile. A duly filled coagulation requisition form (Annexure - CR/05) is mandatory for sample collection. Kindly provide complete clinical details and medication history or a doctor's prescription. This information is important for the correlation of the test results. Inform the doctor about all medications (e.g., blood thinners, anticoagulant medications) and supplements currently being taken, as some of them may affect the test results, potentially requiring dosage adjustments or temporary discontinuation before the test.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Do not self-medicate, and always consult a doctor to understand the test results correctly. This test provides vital information that can guide timely treatment and help prevent future clotting complications.

Please note: This is an outsourced test. The sample is collected by TATA 1MG and processed at a NABL accredited partnered lab.

What does Lupus Anticoagulant (LAC) Profile measure?

Contains 3 tests

The Lupus Anticoagulant (LAC) Profile is a group of blood tests that help measure how lupus anticoagulant antibodies affect blood clotting. These tests include: 

1. Dilute Russell viper venom time (DRVVT) – Screen:

Measures clotting time. Prolonged clotting time suggests the presence of lupus anticoagulant.

2. Activated Partial Thromboplastin Time (APTT):

Assesses the intrinsic clotting pathway. If prolonged, it may indicate inhibitors like lupus anticoagulant.

3. Lupus Anticoagulant Test:

Confirms the presence of lupus anticoagulants (antibodies that target phospholipids and interfere with normal clotting mechanisms).

DRVV Screen

An Activated Partial Thromboplastin Time test measures the time taken by the blood to form a clot. In other words, it is a screening test that helps evaluate a person’s ability to form blood clots. The test analyzes the amount and the function of specific proteins in the blood called coagulation or clotting factors, which are an essential part of blood clot formation.

Blood clotting or coagulation occurs through a series of cascade reactions due to the activation of clotting factors. There are a total of thirteen clotting factors within our bodies that aid in clot formation, and for healthy clot formation, all clotting factors need to be in the right balance. Any imbalance of these factors can lead to a blood clotting disorder.
