What Is A Platelets Count Test?
Platelets are small cell fragments in blood that are essential for blood clotting. Platelets help stop bleeding by clumping together and forming clots at the site of the injury thus playing a crucial role in healing and recovery. The test is often performed to diagnose conditions like thrombocytopenia (low platelet count), thrombocytosis (high platelet count) and other blood-related disorders. It is also used to monitor individuals undergoing medical treatments for leukemia, chemotherapy or autoimmune diseases. Platelet count test is also used to assess overall health of an individual by detecting potential bleeding disorders and ensuring proper blood clot function.
How is the Test Performed?
Sample Collection
The test requires a blood sample which is drawn by a certified healthcare professional.
Lab Analysis
An automated analyzer counts the number of platelets in the blood sample. The process is highly accurate and completely automated.
Result
Results are usually available within a few hours.
What are the symptoms that prompt this test?
Platelet count test is ordered when a patient shows the following symptoms:
Adults
- Unexplained bruising
- Frequent nosebleeds
- Prolonged bleeding from cuts
- Fatigue or weakness
- Petechiae (small red spots on the skin)
- Heavy menstrual bleeding in women
- Unusual bleeding from gums
- Unexplained skin rashes
- Frequent infections (in case of blood disorders)
What are Normal Ranges for This Test?
The normal platelet count ranges between 150,000 to 450,000 per microliter of blood.
Normal ranges are the same for both men and women however pregnancy and certain health conditions may influence platelet levels.
** Normal levels are dependent on a number of factors including age, gender, testing method and health condition of patient etc. Result interpretation should be done by a qualified doctor or healthcare professional.**
What Happens if Test Results Show Abnormal Levels?
If test results show very low platelets level (thrombocytopenia), it may indicate:
- Autoimmune disorders
- Bone marrow diseases
- Severe infections due to bacteria or virus
If platelet levels are too high (thrombocytosis), it may indicate:
- Blood clotting disorders
- Chronic inflammation
- Certain types of cancers
A platelets count test does not diagnose the underlying cause. Further testing such as bone marrow biopsy, clotting tests or genetic analysis are recommended by doctors to determine the exact cause. Your doctor will assess symptoms, medical history and lab test results to provide a proper diagnosis and treatment plan.
