We've all had the occasional black poop, and usually, it's nothing to worry about â food additives like the dye that turns licorice black can tint your poop, too, and in some cases, Pepto-Bismol (really, again?) can even turn your poop black.
4. My report mentions giant platelets.. Giant platelet is a term used to describe platelets that are abnormally large, i.e., as large as a normal red blood cell. These may be seen in certain disorders such as immune thrombocytopenic purpura (ITP) or in rare inherited disorders such as Bernard-Soulier disease.. Mean platelet volume (MPV) and platelet distribution width (PDW) are calculations performed by automated blood analyzers. MPV reflects the average size of platelets present in a person's sample of blood while PDW reflects how uniform the platelets are in size.
Confidence votes 460. Mean platelet volume is the size of the platelets. The higher the MPV the larger the platelet size and the lower the MPV the smaller the platelets. High MPV can cause a person to be at a higher risk for strokes and heart attacks.Low MPV can cause a person to be at risk for bleeding problems (too much bleeding that is slow to stop).ean platelet volume is the size of the platelets. The higher the MPV the larger the platelet size and the lower the MPV the smaller the platelets.
