Activated Partial Thromboplastin Time Test (APTT)

Who Should Get the Activated Partial Thromboplastin Time Test?

The Activated Partial Thromboplastin Time (APTT) test is recommended as part of a broader diagnostic plan. It plays an important role in evaluating clotting performance, particularly in individuals with existing conditions or ongoing treatments. You may be advised to undergo an APTT blood test in the following situations:

• Patients on anticoagulant therapy: Those on heparin require regular APTT monitoring to ensure proper dosing and safety.
• Individuals with liver disease: As the liver synthesises clotting factors, this test helps evaluate clotting in such cases.
• Pre-surgical assessment: The APTT laboratory test is often advised before procedures to minimise bleeding risk.
• Autoimmune conditions: Conditions like lupus may alter clotting; an APTT plasma test helps assess this impact.
• Family history of bleeding disorders: Preventive testing may be recommended for those with genetic risk factors such as haemophilia or von Willebrand disease.

Symptoms That May Require the APTT Test

An APTT test is typically recommended when symptoms suggest a possible clotting issue. These signs should prompt medical consultation and may lead to a recommendation for an APTT test at home or in a certified laboratory. Consider asking your doctor about an APTT blood test if you experience:

• Unexplained or frequent bruising: Especially when bruises appear without any known injury.
• Heavy or prolonged menstrual bleeding: Extended flow may suggest an underlying clotting disorder.
• Recurring nosebleeds or bleeding gums: Persistent episodes may indicate reduced clotting ability.
• Prolonged bleeding from small cuts: Delayed wound healing can reflect clotting inefficiency.
• Visible blood in urine or stool: This may indicate internal bleeding requiring evaluation with an APTT lab test.

How is the Activated Partial Thromboplastin Time Test Done?

The APTT test is a simple diagnostic procedure to evaluate blood clotting. It can be conducted at medical facilities or as an APTT test at home, depending on your preference. The procedure includes:

• Sample Collection: A phlebotomist collects blood from a vein using a sterile needle and a citrate-containing tube to prevent clotting.
• Sample Preparation: The sample is sent to an NABL-accredited lab, where plasma is separated by centrifugation.
• Test Procedure: Lab technicians add reagents to the plasma to trigger clotting and measure the clotting time.
• Home Collection Option: Patients can opt for an APTT blood test at home via MaxAtHome for added convenience.

How to Prepare for the Activated Partial Thromboplastin Time Test

Preparing for the Activated Partial Thromboplastin Time (APTT) test is straightforward. Whether you visit a lab or choose an APTT test at home, these guidelines will help ensure reliable results:

• No fasting required: This is a non-fasting test and can be taken at any time of day.
• Inform your doctor about medications: Blood thinners like heparin may influence test results and should be disclosed.
• Mention any existing health conditions: Especially liver disease, autoimmune conditions, or previous clotting issues.
• Avoid alcohol and intense activity: Doing so 24 hours before the test can improve sample reliability.
• Stay hydrated: Adequate hydration can ease the blood draw during your APTT plasma test at home.

What to Expect When Getting an APTT Test

The APTT test is minimally invasive and straightforward. If you're scheduling an APTT test at home, here's a summary of what to expect:

• Quick and Comfortable Collection: A trained professional will collect the sample using sterile equipment.
• Hygienic Procedures: All safety protocols are strictly followed for home collection.
• No Special Preparation Needed: You don’t need to fast but should mention any medications in use.
• Use of Certified Equipment: The sample is properly labelled and transported under controlled conditions.
• Digital Access to Results: Results of your APTT plasma test are available within 24-48 hours.
• Customer Support: MaxAtHome provides guidance throughout your APTT laboratory test process.

Understanding Your APTT Test Results

The APTT test evaluates how long it takes for your blood to clot. Results should always be interpreted by your doctor in the context of your medical history.

• Normal APTT Range: Generally 25-35 seconds; variation depends on lab protocols.
• High APTT Values may suggest:
• Clotting factor deficiencies (e.g. VIII, IX, XI, or XII)
• Liver dysfunction affecting clotting
• Lupus anticoagulant or clotting inhibitors
• Disseminated Intravascular Coagulation (DIC)
• Use of heparin or other anticoagulants
• Low APTT Values, though rare, may result from:
• Inflammatory or hypercoagulable states
• Certain cancers
• Early vascular or thrombotic conditions
• Clinical Correlation Is Vital: APTT values alone don’t confirm diagnosis - clinical review is essential.

Causes of High APTT Levels

An increased APTT result indicates a delay in blood clotting. Below are some common medical reasons for elevated activated partial thromboplastin time:

• Liver Dysfunction: Conditions like cirrhosis reduce clotting factor production, raising APTT levels.
• Clotting Factor Deficiencies: Genetic disorders such as haemophilia impair normal clot formation.
• Lupus Anticoagulant: An autoimmune factor that disrupts normal clotting without always causing bleeding.
• Disseminated Intravascular Coagulation (DIC): A complex clotting disorder that paradoxically increases bleeding risk.
• Heparin Use: Prolongs APTT intentionally during anticoagulation therapy to prevent clots.
