Platelets are very important for efficient blood coagulation and preventing unnecessary or excessive blood loss. These small, disc-shaped cells usually live for around 5-10 days in the blood before they are destroyed. They are the first cells to be recruited to sites of injury and, when activated, they clump together (aggregate), sealing the blood vessel and forming a blood clot. Platelets are produced in the bone marrow and released into the blood where they play an important role in coagulation (blood clotting), helping to stop bleeding when blood vessels are injured. Platelets are small cell fragments and are found in the blood along with red cells and white cells. We are not a laboratory and are unable to comment on an individual's health and treatment. Lab Tests Online-UK is an educational website designed to provide patients and carers with information on laboratory tests used in medical care. If you are concerned about your test results, you will need to arrange an appointment with your doctor so that all relevant information including age, ethnicity, health history, signs and symptoms, laboratory and other procedures (radiology, endoscopy, etc.), can be considered. If the doctor wants to see you about the result(s), you will be offered an appointment.

Your GP practice will be able to provide specific details. If you are registered to use the online services of your local practice, you may be able to access your results online. The X-ray & scan results may take longer. Some specialist test results may take longer, if samples have to be sent to a reference (specialist) laboratory. On average it takes 7 working days for the blood test results to come back from the hospital, depending on the exact tests requested.
