A Platelet test measures the number of platelets (thrombocytes) in the blood. These small blood cells, which appear as tiny plates under a microscope, play a crucial role in blood clotting, helping stop bleeding after an injury by forming clots. Platelet tests may be requested by doctors during normal checkups or if they suspect disorders like thrombocytopenia (low platelet count) or thrombocytosis (high platelet count). This test primarily aims to monitor or diagnose disorders related to excessive bleeding or clotting and is often included in a complete blood count during regular medical exams. Additionally, it assesses patients with a history of bleeding disorders before surgery and evaluates platelet function during complex surgeries such as cardiac bypass, which have a higher bleeding risk. The test also keeps track of those who are taking blood thinners to prevent clotting in the risk of a heart attack or stroke. Platelet Count testing is also essential for dengue patients, as the virus often decreases platelet counts. Regular Platelet Count tests for dengue patients can help predict and follow recovery from dengue fever (DF), dengue shock syndrome (DSS), and dengue haemorrhagic fever (DHF) directing treatment options.

If you are in Delhi and your doctor has recommended a Platelet Count test for a routine examination or due to any of the reasons mentioned above, getting tested is vital. Arrange for a Platelet Count test in Delhi for yourself or a loved one today.

Below is an overview of how to prepare for the test:

Prerequisites

You do not need to fast for the Platelet test.

Best Time to Get Tested

The Platelet test can be conducted at any time of day.

Who Should Get a Platelet Test

It is suitable for individuals showing signs of elevated platelets, like numbness in the hands and feet, or reduced platelets, such as prolonged bleeding after minor cuts. This test is also important for those on medications to reduce blood clotting or those about to undergo complex surgical procedures.

Cautions Before Taking a Platelet Test

No special cautions are required before taking a Platelet Count test at home.

A Platelet Count in Delhi is necessary when symptoms indicate an abnormal platelet count, either high or low. Symptoms of a low platelet count often include:

• Bleeding for an extended time (following minor cuts or injuries)

• Small red spots on the skin

• Purple patches on the skin

• Bleeding from the nose

• Swollen or bleeding gums

• Bruises (more frequent than usual)

• Blood in urine, stool, or vomit

• Longer or heavier than usual menstrual bleeding

Symptoms of a high platelet count often include:

• Bruises (that are formed easily)

• Dizziness or lightheadedness

• Headaches

• General weakness

• A numbing sensation in the hands and feet

• Nose, gum and mouth bleeds

• Stomach or intestinal bleeding

This test is also required for individuals taking blood-thinning medications and for those undergoing complex surgeries such as trauma surgery or cardiac bypass. It is also important for monitoring conditions that cause excessive bleeding or clotting.

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:

• Dengue fever

• Contact with harmful chemicals like arsenic

• Severe bleeding following an injury

• Bacterial or viral infections

• Drinking excess alcohol

• Certain medications like antibiotics

• Diseases in which the body attacks its own healthy cells like rheumatoid arthritis

• Genetic disorders such as Von Willebrand disease

• Blood disorders like thrombotic thrombocytopenic purpura

• Blood cancers such as leukaemia

• Treatment for cancers such as chemotherapy

A reduced platelet count might be due to conditions like haemolytic uremic syndrome, which depletes or destroys platelets. Furthermore, the spleen can sometimes trap platelets, hindering their circulation in the bloodstream.

High Count

Reasons for a high platelet count include:

• Undergoing treatment for vitamin B12 deficiency

• Reactive Thrombocytosis

• An injury

• Certain medications like adrenalin

• Bacterial or viral infections

• Inflammatory conditions like rheumatoid arthritis

• Blood disorders like anaemia

• Spleen removal

• Failure of kidney

• Certain surgical procedures like abdominal surgery

• Certain cancers such as breast cancer

A hereditary disorder involving a JAK2 gene mutation can result in a high platelet count, as it causes the bone marrow to increasingly produce excess platelets over time.
