Blood platelet count - should it go up or down if I have the flu?

Either way... Viruses can cause suppression of the bone marrow causing any combination of anemia, low platelets, and low white blood cells. After you recover from the virus, your bone marrow will recover and so will your counts. If they don't, other causes will need to be considered. In addition, some people develop immune thrombocytopenic purpura after an illness (an autoimmune destruction of platelets).
No it should go UP. Platelets are an acute phase reactant, along with esr, crp, and plasma viscosity. If your platelets go down in response to an illness, it can be a sign of a platelet-lowering disease such as felty syndrome (and many others).

If they are not being produced effectively, there is a good chance that other types of blood cells aren't being produced well either. Read more...
Splenectomy. To add to dr. Sample's excellent answer...A common cause of thrombocytopenia is itp (idiopathic thrombocytopenic purpura) where platelets are deformed by antibodies causing their destruction by the spleen.

What is the definition or description of: blood platelet count?

Blood clotting cell. Platelets are blood cells that assist in forming clots. They are produced by megakaryocytes in the bone marrow they adhere to one another in the face of trauma to form a seal. A normal platelet count is about 200, 000 to 400, 000 platelets per microliter. Read more...
Thrombocytes. Platelets, or thrombocytes are small, irregularly shaped clear cell fragments which are derived from fragmentation of precursor megakaryocytes. The average lifespan of a platelet is normally just 5 to 9 days. They circulate in the blood and are involved in hemostasis, leading to the formation of blood clots. Platelet count is the number of platelets in blood. Read more...

Several things. Platelets are a blood product we make that has a very limited lifespan, counted in hours rather than the months our red cells stick around. A reduced count means less are being made or more are being destroyed by some process in the body.Sometimes a low count can just reflect a sampling error, where the platelets clumped up and the machine did not count the true number.
