Platelet Count Test in Delhi
Platelet Count Blood Test in Delhi
What are platelets?
Clotting is a process that aids in the cessation of bleeding. Platelets, also known as thrombocytes, are blood cells critical for clotting. These are pretty tiny in size and are often discovered in the bloodstream at the site of the damage. Platelets aggregate at the site of damage and form a mesh-like layer, which can help reduce bleeding and form a clot in that location.
What is a platelet count test?
A platelet count test determines the number of platelets in your blood. A person possesses between 150,000 and 450,000 platelets per microliter of blood. Thrombocytopenia is when platelets are lower than the typical average level. A person with thrombocytopenia cannot produce blood clots effectively and may bleed profusely after a slight cut or injury. In contrast, thrombocytosis occurs when the normal platelet count exceeds the average platelet count. In contrast to thrombocytopenia, when a person has thrombocytosis, their blood clots excessively regardless of any damage or the need for clotting. Blood clots are extremely harmful because they can impede blood flow in unexpected areas if they circulate in the bloodstream.
What are the uses of a platelet count test?
Doctors often advise patients to have a platelet count test as part of their regular clinical checkup. It is frequently used to determine whether a person's platelets are within the normal range. A platelet count test can also aid in the early detection of illnesses and determine whether a person is a danger of excessive bleeding. In general, a Platelet blood test can be included in a complete blood count test, which can provide information on several other parameters. A platelet count test is highly recommended for dengue patients.
How should the results of a platelet count test be interpreted?
The normal platelet count can easily detect the average platelet level in the blood. The chart below shows the average platelet level and suggests whether a patient has a high platelet level or a low platelet level.
Platelet count
Result (per ml of blood)
High Platelet level (thrombocytosis)
more than 450,000
Normal platelet count
150,000–450,000
Low Platelet level (thrombocytopenia)
less than 150,000
What are the reasons for elevated platelet counts?
When a person's platelet count is high, the bone marrow generates an abnormally large number of platelets. Primary or essential thrombocytosis is the medical term for this illness. Excess platelets can also suggest an infection in the body, known as secondary thrombocytosis. Some of the most common causes of a high platelet count are:
Recovering from a recent injury that caused excessive blood loss
Suffering from a severe infection such as dengue
Excessive vitamin B12 consumption
Putting oneself through strenuous physical activity and exertion
A high platelet count can be caused by lung, stomach, and ovarian lymphoma cancers
A high platelet count accompanies anaemia
Tuberculosis infections
Rheumatoid arthritis and inflammatory bowel disease are examples of autoimmune diseases causing high platelet count
Undergoing splenectomy surgery
What factors contribute to a low platelet count?
A person's platelet count might be low for a variety of causes. The following are some of the most prevalent reasons for a low platelet count:
Platelet levels in the blood have been proven to be depleted by viral infections such as AIDS, HIV, and hepatitis.
Medications: Excessive medication intake, such as aspirin, quinidine, or antibiotics, may or may not diminish platelet count.
Cancer that has progressed to the bone marrow might impair its capacity to make new platelets, resulting in a drop in platelet count.
A chronic illness, such as a blood infection termed sepsis, can cause a decrease in platelet count.
Some autoimmune diseases, such as lupus and Crohn's disease, have also been linked to a low platelet count.
Who should have this test done?
If a person exhibits signs of having few platelets, they may require a specific test. Some of the signs of low platelet count include:
Bleeding over an extended time following a small cut or injury
The development of a blood clot is delayed.
Bruising all over the body for no apparent reason
A menstrual cycle that is unusually heavy and lengthy
Nosebleeds are common.
Many red dots on the skin of a person are known as petechiae.
People with a low platelet count will also have a distinct purple area on their skin, known as purpura. This purple area is typical since it is caused by bleeding beneath the skin.
When a person has an excess of platelets, the following are some of the most typical symptoms:

Blood platelet levels are sometimes seen in alcoholics and may be caused by an alcohol-induced enlarged spleen (splenomegaly), folate (one of the B vitamins) deficiency, but most frequently, a direct toxic effect of alcohol on production, survival time, and function of platelets. Platelet count begins to rise after 2 to 5 days' abstinence from alcohol. The alcohol-induced condition is generally reversible with abstinence, and clinically significant hemorrhage is rare.

The platelet aggregation test checks to see how well platelets, a part of blood, clump together and cause blood clotting.
How the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.
Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
The laboratory specialist will look at how the platelets spread out in the liquid part of the blood (plasma) and whether they form clumps after a certain chemical or drug is added. When platelets clump together, the blood sample is more clear. A machine measures the changes in cloudiness and prints a record of the results.
How to prepare for the testMany medications may affect test results. Tell your health care provider about any medications (including over-the-counter drugs) you have taken within 2 weeks before the test.
Medications that may alter test results include:
- Aspirin
- Aspirin compounds
- Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen
- Tricyclic antidepressants
- Antihistamines
- Some antibiotics
When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
Why the test is performedYour doctor may order this test if you have signs of a bleeding disorder or low-platelet count, or if a member of your family has a known bleeding disorder due to platelet dysfunction.
The test can help diagnose problems with platelet function and determine whether the problem is due to your genes, another disorders, or even a side effect of medicine.

Normal ValuesThe normal time it takes platelets to clump depends on temperature and may vary from laboratory to laboratory.
What abnormal results meanDecreased platelet aggregation may be due to:
- Autoimmune disorders that produce antibodies against platelets
- Bernard-Soulier syndrome
- Certain medicines that block platelet formation
- Glanzmann's thrombasthenia
- Myeloproliferative disorders
- Fibrin degradation products
- Storage pool disease
- Uremia (a result of kidney failure)
- Von Willebrand's disease
There is very little risk involved with having your blood taken. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.
Other risks associated with having blood drawn are slight but may include:
- Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
Note: This test is often performed because the patient has a bleeding problem. Bleeding may be more of a risk for this person than for people without bleeding problems.

A test for platelet-associated antibodies shows whether you have antibodies that are directed against platelets in your blood.
How the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The area is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.

How to prepare for the testNo special preparation is necessary for adults.
How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
Why the test is performedThis test may be ordered when you have a low platelet count (thrombocytopenia). It is used to detect antibodies against platelets.
Normal ValuesA negative test is normal.
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results meanAbnormal results show that you have antiplatelet antibodies. These are proteins made by the body that attach to platelets and destroy them. This causes a low platelet count, which can lead to excessive bleeding.
Antiplatelet antibodies may appear in the blood for unknown reasons (idiopathic thrombocytopenic purpura), or as a side effect of certain drugs such as heparin. These drugs can sometimes cause the immune system to identify its own platelets as abnormal or foreign, and attack them.
What the risks areVeins and arteries vary in size from one patient to another, and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
Other risks associated with having blood drawn are slight but may include:
- Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
Current tests cannot tell for sure whether a low platelet count (thrombocytopenia) is caused by immune problems. Therefore, your doctor will make a diagnosis based on other tests and examinations.
This test is often performed because you have a bleeding problem. Bleeding may be more of a risk for you than for people who do not have bleeding problems.

No, a hyperactive spleen does not directly cause platelet deficiency. Platelet deficiency is typically due to decreased platelet production in the bone marrow or increased platelet destruction in the body, such as in immune thrombocytopenia. However, a splenic disorder or enlargement can sometimes lead to increased platelet destruction and contribute to low platelet levels.

That is lower than normal but not dangerous by itself. The most common reason is lab error so the first step is to repeat it and have the lab look under the micrpscope to confirm the machine's finding.
If it is still low then you should talk to your doctor about why it might be.

platelet transfusions do not succeed in raising the platelet levels for long. Often people need platelet every 12 - 24 hrs if they are not making them on their own. The real issue is why are they not making platelet's and to try and get their body to do so. This is often seen with cancer and thrombocytopenia. The effect of low platelets is a risk of bleeding since platelet are an important clotting factor. Ive never been impressed with platelet transfusions they are not anywhere near as good as what a healthy body does naturally.
