Platelets bind together forming a blood clot to stop bleeding
The platelet count is a part of a complete blood test
Normal platelet count is between 1,50,000 and 4,50,000 per µL of blood
Platelets are fragments of larger cells made in the bone marrow known as megakaryocytes . They are also known as thrombocytes. These cells circulate in your blood and form blood clots when there are damaged blood vessels . For instance, if you get hurt and are cut, the platelets will form a blood clot to stop bleeding. A platelets count test is part of a complete blood count (CBC) test . It measures the number of platelets in your blood.
A high platelet count or a low platelet count can be a sign of certain medical conditions. Read on to know what high and low platelets suggest and what should be the platelets normal range.
Platelets count is a test done to know the number of platelets in your blood. It may be used to diagnose or monitor conditions that affect the number of platelets. These conditions include:
It may be used to screen for diseases that cause problems with blood clot formation as well.
A platelets test may be ordered as a part of a complete blood test for a routine health checkup. Your doctor may order this test if you show signs of low platelets or bleeding disorders. Some of these symptoms can be:
The platelets count test may also be ordered if your doctor suspects that you have too many platelets. This is also known as thrombocytosis. It may cause excessive clotting or bleeding. Sometimes, you may not experience any symptoms. So, a PLT blood test helps check if there are any health conditions.
A high platelet count is medically known as thrombocytosis. There are two types:
Symptoms such as spontaneous blood clots in the arms and legs can lead to heart attack and strokes. In serious cases, a person may have to undergo the platelet apheresis  procedure. Here, blood is removed, the platelets are separated and returned with the blood to the body. In the case of secondary thrombocytosis, the symptoms are usually linked with an associated condition such as infection and anemia. Treating these conditions brings down count well below the PLT normal range.
A low platelet count is called thrombocytopenia. Some symptoms of this health issue are:
Various issues prevent your body from producing platelets and causes a dip in the count. Some of these causes can be:
Some other factors that cause low platelet count are:
The use of certain drugs such as aspirin, ibuprofen, certain antibiotics, and diuretics are also associated with decreased platelet count. Bone marrow damage caused by toxic chemical exposure such as pesticides and benzene also result in low platelets.
A platelet count normal range is from 1,50,000 to 4,50,000 platelets per microliter of blood. If you have less than 1,50,000 platelets, this condition is known as thrombocytopenia. A high platelet count is when your platelets are more than 4,50,000 per microliter of blood. This is called thrombocytosis.
If you have an abnormal platelet count range, your doctor may order additional tests such as CRP or ESR. A low platelet count can be treated by addressing the underlying causes. It is important that you get tested often to keep these levels in check. Book an appointment with a doctor or a lab test easily on Bajaj Finserv Health.
