Platelet Count
A platelet count is a test that measures the number of platelets in a person's blood sample. Platelets are tiny cells that are important for clotting and prevent bleeding.
Preparation for Platelet Count Test
No special preparation is needed for the test. The patient may have to fast (not eat or drink) for 8 to 12 hours before the test.
Procedure for Platelet Count Test
A blood sample is taken from the patient and sent to a laboratory. The lab counts the number of platelets in the blood sample to get the platelet count.
Types of Platelet Count Tests
- Complete Blood Count (CBC): The CBC measures the size, number, and condition of all the different types of cells in a person's blood, including platelets.
- Manual Platelet Count: This test is done by looking at a sample of a person's blood through a microscope and counting the number of platelets.
- Automated Platelet Count: This test is done by a machine and is more accurate than a manual platelet count.
Risks of Platelet Count Test
The risks of having a platelet count test are minimal. The patient may experience some minor discomfort during the blood draw.
Why Measure Platelet Count?
Doctors measure platelet count to help diagnose and monitor conditions that affect the number of platelets, such as leukemia and other blood disorders. Platelet count may also be used to monitor the effectiveness of treatments for these conditions.
When Should Platelet Count Be Measured?
Platelet count should be measured when a person is exhibiting symptoms of a blood disorder or if they have a family history of a blood disorder. Platelet count may also be measured as part of a regular checkup to monitor the health of a person.
