Therefore platelet parameters are markers that are thought to be increased in response to systemic inflammation, and various studies have stated the relationship between these parameters and different inflammatory disease. Variation in platelet size is indicative of change in platelet function. The platelet distribution width (PDW) is the width of the size distribution curve in femtoliter (fL) at the 20% level of the peak on the impedance platelet size distribution curve. MPV is a potential marker of the platelet reactivity. Mean platelet volume (MPV) is calculated by dividing the plateletocrit (PCT) by the number of platelets, and therefore PCT is analogous to the red cell haematocrit. Size-related parameters are derived from the impedance platelet size distribution curve. Automated blood cell counters provide a platelet count and derive indices relating to the size of platelets. Over the last few years, several new and reportable parameters have been used in the routine complete blood count (CBC) analyzers. Activated PLTs can promote vascular inflammation, causing endothelial inflammation and subsequent leukocyte extravasation via their stored cytokines and chemokines.
In addition to the fact that the central role of the platelets is to control bleeding and to induce thrombosis, they have different roles in inflammation, atherosclerosis, angiogenesis, antimicrobial host defense, and contribution to wound healing. They provide rapid protection against bleeding and catalyze the formation of stable blood clots. It’s closely related to a platelet count test, which measures the number of platelets in your blood.Platelets (PLTs) play an important role in the primary hemostasis and arterial thrombosis formation. An MPV test measures the average size of your platelets. One of the tests run during a CBC is a mean platelet volume (MPV) test. A complete blood count (CBC) is a panel of tests routinely performed in people living with HIV that measures the composition of white blood cells, red blood cells, and platelets in a sample of blood. If you had a rapid screening test, the testing site will arrange a follow-up test to make sure the screening test result was correct.Ī high platelet count is rarely problematic. If the follow-up test is also positive, it means you are HIV-positive. What Does a Positive HIV Test Result Mean? If you have a positive HIV test result, a follow-up test will be conducted. What does a positive HIV test result mean? Larger platelets are usually young and more recently released from the bone marrow. Platelets are produced in the bone marrow and released into the bloodstream. This is sometimes a sign that you’re producing too many platelets. What does a high MPV mean on a blood test?Ī high MPV means that your platelets are larger than average. To learn what your results mean, talk to your health care provider. It may also indicate marrow hypoplasia, a disorder that causes a decrease in blood cell production. A high MPV with a low platelet count may indicate that the platelets you make are going into circulation very quickly.Ī low MPV can indicate exposure to certain drugs that are harmful to cells. Mean Platelet Volume (MPV): The average size of your platelets (range 8 -12).
HIGH MPV NORMAL PLATELET COUNT SKIN
Superficial bleeding into the skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on the lower legs.– Normal platelet count along with high MPV suggests conditions such as hyperthyroidism or chronic myelogenous leukemia (CML). – High platelet count along with high MPV can occur when the bone marrow produces too many platelets, typically due to a genetic mutation or cancer. What does high MPV and normal platelet count mean?
In general, smaller platelets tend to be older, so a low MPV may mean that bone marrow is not producing enough new platelets. Numbness or tingling of the hands and feet.Ī low MPV means that platelets are smaller than average.MPV Normal Range The normal MPV range is around 7-12 fL (fL= one femtoliter, a very small unit of blood).
