Hi, I am Stefania Brown, I am the Laboratory Manager at One Day Tests and here are the lab's special requests for the Ultimate Coagulation (Clotting) Blood Test.

There are no special instructions for this specific test.

Venepuncture appointment - how to prepare

If you are coming into one of our clinics for the test, this is what you need to do before you arrive:

  • Drink plenty of water about an hour before the appointment.
  • Avoid coffee/tea/energy drinks. Water is good!
  • That’s it! We’ll do the rest.

Home test kit for Ultimate Coagulation (Clotting) Blood Test - how it works

Our blood test kits are simple and convenient.

The most important step in doing a blood test at home is to read the instructions very carefully. The process is very simple, but there are a few pitfalls you need to be aware of - you will save yourself a lot of time if you do it right the first time around!

  • Full printed instructions will arrive with your kit - please read them carefully.
  • Drink plenty before taking the sample and warm your hands up in the sink with warm water for a few minutes. This will make your blood flow much better.
  • Fill the tubes to the top line. We don’t need much blood; filling tubes to the top line is about 15 drops of blood.
  • Post the samples on the same day you take them, before midday, Monday to Thursday. If you post it any other time it might get to us late or be stuck at a sorting office over the weekend. You will then have to do it again.
  • Package the sample in the same box the kit came in. Otherwise, Royal Mail or DPD will reject it. The sample tubes go into a pouch, then into a cardboard box, and then into a return envelope. All of this is provided in the kit: please use it.

We look forward to receiving your sample in our lab!

Frequently Asked Questions

Hi, I am Lana Nela, Lead Nurse, and here is what we are frequently asked about this test.

What is a coagulation blood test, and what does it measure?

A coagulation blood test is a diagnostic test that assesses the clotting function of the blood. It measures various parameters such as clotting time, clotting factors, platelet count, and other coagulation markers to evaluate the blood's ability to form clots effectively. The test helps diagnose clotting disorders, monitor anticoagulant therapy, and evaluate liver and kidney function related to coagulation.

What are D-Dimers?

D-dimers are small protein fragments that are produced when a blood clot is broken down in the body. They are formed during the degradation of fibrin, a protein involved in the formation of blood clots. D-dimer levels can be measured through a blood test and are used as a marker to evaluate the presence or likelihood of an active blood clotting process in the body.

D-dimer tests are commonly used in the diagnosis and management of conditions such as deep vein thrombosis (DVT), pulmonary embolism (PE), and disseminated intravascular coagulation (DIC). When a blood clot forms, it eventually breaks down, releasing D-dimers into the bloodstream. Elevated levels of D-dimers can indicate an ongoing clotting process, suggesting the need for further investigation or treatment.

Why take this test?

Hi, I am Dr. Marco Esposito and here is why it's important to take this test.

The coagulation blood test plays a crucial role in assessing and monitoring the clotting function of the blood, making it an important diagnostic tool in healthcare.

Blood clotting, or coagulation, is a vital process that prevents excessive bleeding when a blood vessel is injured. This test helps identify various clotting disorders and abnormalities that can lead to either excessive clotting or excessive bleeding.

By measuring parameters such as clotting time, clotting factors, platelet count, and other coagulation markers, healthcare professionals can diagnose conditions such as hemophilia, von Willebrand disease, deep vein thrombosis (DVT), and disseminated intravascular coagulation (DIC).

It is also used to monitor patients on anticoagulant therapy, ensuring that their blood is within the desired therapeutic range to prevent both clotting and bleeding complications.

Is this test right for you?

Hi, I am Sandeep Patel, I am the Laboratory Director at One Day Tests. Here are the symptoms that you may wish to address with this test.

Coagulation tests, also known as clotting tests, are conducted to assess the body's ability to form blood clots effectively. They are commonly used to diagnose bleeding disorders, monitor the effectiveness of anticoagulant medications, or evaluate liver and kidney function. If you have a family history of clotting disorders, experience excessive bleeding or bruising, or are undergoing certain medical treatments, such as surgery or long-term medication use, a coagulation blood test may be useful.

Finally, if you are experiencing unexplained symptoms like frequent nosebleeds or heavy menstrual bleeding, your GP may find this test useful in determining the underlying cause.
