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.
Definition of Platelets. Platelets are tiny cell fragments that are found within our blood. They originate in the bone marrow as pinched-off pieces of larger cells. Platelets are neither smooth nor round, but are shaped more like paper that has been ripped into tiny bits. They spend much of their time cruising through the bloodstream alongside their red and white blood cell counterparts.
