What number is a dangerous platelet count?
What Platelet Count Is Dangerously Low? A platelet count of 20,000 or fewer per microliter is considered dangerously low, according to the University of Pittsburgh Medical Center. Internal bleeding or other complications can result from very low platelet counts, which can be fatal if the bleeding affects the brain or the intestines.
How do you estimate platelet count?
- Increased (Incr.): The count is above the reference interval for the species.
- Adequate (Adeq.): The count is within the reference interval for the species.
- Low?: The count is within the low end of the reference interval for the species or may be mildly decreased (i.e. ...
- Low: The count is below the reference interval for the species.
What are the causes of elevated platelet count?
The causes of high platelet count or thrombocytosis can be classified as follows:
- Physiological thrombocytosis
- Reactive (secondary) thrombocytosis
- Clonal (primary) thrombocytosis
What is a dangerous platelet count?
If your platelet count is below 50,000 (50 × 10 9 /L), your risk for bleeding is higher. Even every day activities can cause bleeding. A lower-than-normal platelet count is called thrombocytopenia. Low platelet count can be divided into 3 main causes:
Is 500 high for platelets?
Normal Results The normal number of platelets in the blood is 150,000 to 400,000 platelets per microliter (mcL) or 150 to 400 × 109/L. Normal value ranges may vary slightly. Some labs use different measurements or may test different specimens. Talk to your doctor about your test results.
What is the alarming level of platelets?
A normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis; having less than 150,000 is known as thrombocytopenia.

Should I worry about a slightly elevated platelet count?
There are many reasons why your platelet counts could be high, most of which are acute and nothing to worry about. However, a high platelet count can be serious if it's a sign of disease or other health condition, such as cancer or inflammatory bowel disease (IBD).
What is the most common cause of high platelet count?
With primary thrombocythemia, a high platelet count may happen alone or with other blood cell disorders. This condition is not common. Thrombocythemia is most often caused by your genes. Mutations, or changes, in the genes that control how your bone marrow forms platelets may cause thrombocythemia.
What does a platelet count of 475 mean?
Platelets are the cells that help your blood to clot, and if you have ET, your bone marrow may be producing too many of these cells. A normal platelet count is 150 to 450 –– counts above 450 are considered higher than normal.

What causes platelets to rise in the bone marrow?
A mutation in the CALR gene can also cause too many platelets to be made in the bone marrow. 2. Secondary thrombocytosis can also be called reactive thrombocytosis, as the platelets rise in response to something outside of the bone marrow, such as an infection, inflammation, or bleeding. 3.
Why are there so many platelets in the blood?
In primary thrombocytosis —also referred to as essential thrombocythemia—the high number of platelets being made is due to an abnormality in how the bone marrow is making them. A mutation may exist in the JAK2 gene, which causes an enzyme to work too much at making platelets. A mutation in the CALR gene can also cause too many platelets ...

The myeloproliferative disorder that causes too many platelets to be made is called essential thrombocythemia, introduced above.
Why are my platelets elevated?
Though these may seem like significant numbers, it is important to remember that the majority of elevated platelet counts are caused by a reactive process, such as infection or inflammation. Once the cause of the reactive process resolves, platelet counts generally return to normal levels.
Can high platelet count cause blood clots?
It is possible, however, that having high platelet counts can lead to the development of blood clots. Blood clots can potentially form in any blood vessel, but most commonly form in the blood vessels in the arms and legs, or in the blood vessels in the brain. These clots can prevent blood from flowing properly through these vessels, ...

Useful Information
Platelets, also called thrombocytes are a component of blood whose function (along with the coagulation factors) is to stop bleeding by clumping and clotting blood vessel injuries.

Keri Peterson, MD. on May 11, 2020. In general, a platelet count more than 450,000 cells per microliter is considered elevated; this is known as thrombocytosis. There are numerous causes of thrombocytosis and fortunately, the majority are benign and transient.
What causes blood clots in et?
With these conditions, the excessive numbers of platelets cause the blood to be thick and flow more slowly which may result in blood clots. Treatment is aimed at reducing the platelet count to reduce this risk. 2 .
What causes thrombocytosis?
Conditions with inflammation, like rheumatologic disorders, inflammatory bowel disease, and vasculitides, can have thrombocytosis. 5 The elevated platelet count occurs in response to cytokines (small proteins released from cells that signal other cells to do something). In particular, the cytokines interleukin-6 and thrombopoietin stimulate platelet production.
Can cryoglobulinemia cause platelet elevation?
Mixed cryoglobulinemia can cause a false elevation in the platelet count. 6 In this condition, cryoglobulins (proteins) in the blood stick together when exposed to cold temperatures (like the hands and feet).
Can hemolytic anemia cause platelets to be inaccurately counted?
If hemolytic anemia (anemia secondary to red blood cell fragmentation) results in the formation of very small red blood cells, these red blood cells may be inaccurately counted as platelets by the machine that performs the complete blood count.
Can low platelet count cause thrombocytosis?
At this time, it is unknown what exactly causes this thrombocytosis. In general, it is well tolerated and resolves with appropriate iron supplementation treatment. 3
What is high platelet count?
High platelets is a condition in which the blood contains more platelets than normal. Platelets are small blood cell fragments that assist in blood clotting. In a healthy person, there are usually 150,000 to 450,000 platelets per microliter of blood. A high platelet count can be identified through routine blood tests.
How to identify high platelets?
A high platelet count can be identified through routine blood tests. The occurrence of high platelets is divided into two medical categories: primary thrombocythemia and secondary thrombocytosis. In primary thrombocythemia, the cause of the high platelets is not known, and it occurs as an independent condition.
What is thrombocythemia?
Thrombocythemia is a condition in which high platelets occur as an independent condition without another known cause. In this condition, the bone marrow makes too many platelets. This condition may be inherited.
What does it mean when your platelets are high?
In secondary thrombocytosis, high platelets occurs as a symptom of another disease or condition, such as anemia, infection or cancer. In many cases, high platelets may not produce specific symptoms. In other cases, the elevation in platelet levels leads to the development of unwanted and unnecessary blood clotting throughout the body, ...

If the cause is due to previous surgery or injury that have resulted to a significant loss of blood, thrombocytosis will not last long. If the cause is due to chronic infection or inflammatory disease, platelet levels may remain elevated until the condition is brought into control.
What is the definitive diagnosis of elevated platelet count?
The definitive diagnosis can be made after relevant laboratory procedures and measurements of platelet levels. Elevated platelet count causes symptoms that may also require the analysis to be carried further for the identification of associated factors like anemia and increase in leukocytes.
