A Platelet test counts the number of platelets (thrombocytes) in the blood. These small blood cells, which resemble tiny plates under a microscope, are vital for blood clotting, stopping bleeding after an injury by forming clots. Doctors may order a Platelet test during routine physical exams or if there is a suspicion of conditions like thrombocytopenia (low platelet count) or thrombocytosis (high platelet count). This test primarily serves to monitor or diagnose disorders associated with excessive bleeding or clotting and is frequently part of a complete blood count in standard medical checkups. It also assesses platelet function in complex surgeries such as cardiac bypass, which carries a higher risk of bleeding, and evaluates patients with a history of bleeding disorders before surgery. The test is used to monitor individuals on blood-thinning medications, which reduce clotting in those at risk for heart attacks or strokes. In addition to this, Platelet Count testing is particularly important for dengue patients, as the virus can lower platelet counts. Regular Platelet Count tests for dengue patients help predict and follow recovery from dengue fever (DF), dengue haemorrhagic fever (DHF), and dengue shock syndrome (DSS), influencing treatment options.

Platelet Count Test Parameters
Platelets play a crucial role in preventing excessive bleeding after injuries. These smallest blood cells are only visible under a microscope. When inactive, platelets have a plate-like shape. Upon injury, damaged blood vessels release signals that activate platelets. These platelets then travel to the wound, transform into their spider-like active form, and cluster to form a plug that seals the vessel, stopping further blood loss. Without this mechanism, even minor injuries could result in critical blood loss.
The Platelet Count test has only one parameter: it measures the number of platelets in the blood.
Platelet Count Test Preparation
Below is an outline of the test's preparation:
Prerequisites
Fasting is not necessary for the Platelet Count test.
Best Time to Get Tested
You can take the Platelet test at any time of the day.
Who Should Get a Platelet Test
This test is recommended for those with symptoms of platelet deficiency, such as prolonged bleeding from minor cuts, or of excess platelets, such as numbness in the hands and feet. It is also crucial for individuals scheduled for complex surgeries or those using medication to reduce blood clotting.
Cautions Before Taking a Platelet Test
No special preparations are necessary before taking a Platelet Count test at home.
Why Take a Platelet Count Test?
If symptoms suggest an abnormal platelet count (high or low), a Platelet Count in Hyderabad is crucial. The following are common symptoms of a low platelet count:
Bleeding for a long time (following minor cuts or injuries)
Bruises (more frequent than usual)
Bleeding from the nose
Small red spots on the skin
Purple patches on the skin
Blood in urine, stool, or vomit
Swollen or bleeding gums
Longer or heavier than usual menstrual bleeding
The following are common symptoms of a high platelet count:
A numbing sensation in the hands and feet
Dizziness or lightheadedness
General weakness
Bruises (that are formed easily)
Headaches
Nose, gum and mouth bleeds
Stomach or intestinal bleeding
This test is also important for patients undergoing complex surgeries like cardiac bypass or trauma surgery, or those on blood-thinning medications. It is also useful for monitoring conditions that lead to excessive bleeding or clotting.
Platelet Count Test Results & Interpretation
The result of a Platelet Count Blood test is given below:
Normal range: 150-450 [10^3/µL]
Low Count
Reasons for a low platelet count include:
Drinking excess alcohol
Severe bleeding following an injury
Dengue fever
Bacterial or viral infections
Certain medications like antibiotics
Diseases in which the body attacks its own healthy cells like rheumatoid arthritis
Contact with harmful chemicals like arsenic
Blood disorders like thrombotic thrombocytopenic purpura
Blood cancers such as leukaemia
Genetic disorders such as Von Willebrand disease
Treatment for cancers such as chemotherapy
Diminished platelet supply, such as from conditions like haemolytic uremic syndrome that destroys platelets, can lead to a low platelet count. Additionally, platelets may sometimes get trapped in the spleen, preventing them from entering the bloodstream.
High Count
Reasons for a high platelet count include:
Bacterial or viral infections
Reactive Thrombocytosis
An injury
Undergoing treatment for vitamin B12 deficiency
Inflammatory conditions like rheumatoid arthritis
Failure of kidney
Certain medications like adrenalin
Spleen removal
Blood disorders like anaemia
Certain surgical procedures like abdominal surgery
Certain cancers such as breast cancer
A high platelet count may arise from a hereditary disorder linked to a JAK2 gene mutation, prompting the bone marrow to overproduce platelets progressively.
