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.
1 The platelet count is the number of platelets in a person's sample of blood. 2  Mean platelet volume (MPV) may be reported with a CBC. It is a calculation of the average size of platelets.  Platelet distribution width (PDW) may also be reported with a CBC. It reflects how uniform platelets are in size.
