When you don’t have enough platelets, it’s called thrombocytopenia. For example, if you have an infection or anemia, you treat those conditions and the platelet count comes down. With secondary thrombocytosis, the symptoms are usually related to the associated condition. This lowers the platelet count by removing the blood, separating out the platelets, and returning the red blood cells back to the body. In severe cases, the patient might have to undergo a procedure called a platelet pheresis. When there are symptoms, they include spontaneous blood clots in the arms and legs, which if untreated can lead to heart attack and stroke. Secondary thrombocytosis – The same condition as primary thrombocytosis, but may be caused by an ongoing condition or disease such as anemia, cancer, inflammation, or infection.Primary or essential thrombocytosis – Abnormal cells in the bone marrow cause an increase in platelets, but the reason is unknown.The medical term for having too many platelets is thrombocytosis, and there are two types:
You get your platelet number from a routine blood test called a complete blood count (CBC). Having more than 450,000 platelets is a condition called thrombocytosis having less than 150,000 is known as thrombocytopenia. What is a healthy platelet count?Ī normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. To make contact with the broken blood vessel, platelets grow long tentacles and then resemble a spider or an octopus. When platelets receive that signal, they’ll respond by traveling to the area and transforming into their “active” formation. A blood vessel will send out a signal when it becomes damaged. They’re literally shaped like small plates in their non-active form. Platelets, the smallest of our blood cells, can only be seen under a microscope. It’s to stop us from bleeding.” What makes platelets change their shape? There’s an evolutionary reason why they’re there. “When you get a cut, for example, the platelets bind to the site of the damaged vessel, thereby causing a blood clot. “Platelets are the cells that circulate within our blood and bind together when they recognize damaged blood vessels,” says Marlene Williams, M.D., director of the Coronary Care Unit at Johns Hopkins Bayview Medical Center.
