The red blood cell distribution width (RDW or RCDW) is a measure of the variation of red blood cell (RBC) width that is reported as part of a standard complete blood count. Usually red blood cells are a standard size of about 6-8 μm. Certain disorders, however, cause a significant variation in cell size. Higher RDW values indicate greater variation in size. Normal reference range in human red blood cells is 11-15%. If anemia is observed

My RDW-SD was 37.80 fl

low in B12 or iron
nothing if the RDW and MCV are normal

Means that the variation in the size of your red blood cell is very small. That it! Inother words, no problem!RDW refers to the variation in size if your red blood cells.A low RDW means that the cells are all roughly the same size.A high RDW means there isa high variation in the sizes of the cells and usually means a deficiency of iron and/or B12.

Well to all the people who are interested: These are hematological parameters that indicate an underlying anemic condition. The normal RBC is spherical and biconcave with a diameter of 6-8 micrometer. any variation in size is termed as anisocytosis and in shape is termed as poilikocytosis. These variations are seen in anemic conditions like iron or folate or Vitamin B12 deficiency or others. Earlier when blood samples were analyzed manually under microscope the terms aniso and poikilocytosis were used, when such variations were observed, but with the advent of computerized automated blood analysis methods newer terms like RDW, RDW-SD, RDW-CV have come into place, these terms also indicate unusual variations in the size and shape of RBC which are highly indicative of a possible Anemic conditions. RDW stands for Red Cell Distribution Width RDW- SD stands for Standard Deviation in RDW RDW-CV stands for Coefficient Variation of RDW These are technical terms used in computer interpretation of the given blood samples If your reports show abnormal values do consult your physician .

The quantitation of platelets in peripheral blood is a well-recognized tool. Recently, new indices related to erythrocytes and platelet counts have been provided by hematologic analyzers. Concerning the platelet parameter, the three important parameters are plateletcrit (PCT), mean platelet volume (MPV), platelet distribution width (PDW). The purpose of the study is to investigate these three parameters to define their expected values and the correlation with the parallel red blood cell parameters, hematocrit (HCT), mean corpuscular volumer (MCV), and red blood cell distribution width (RDW). Blood samples form 215 volunteers were analyzed for platelet parameters using Technicon H*3. The average (mean ± SD) values obtained with expected ranges were PCT 0.24 ± 0.05% (range, 0.23-0.24%), MPV 12.79 ± 5.91 fL (range, 12.39-13.19 fL), and PDW 46.79 ± 2.70% (range, 46.61-46.97%). Concerning the correlation between PCT, MPV, and RDW and their parallel red blood cell parameters, there was no significant correlation between PCT and HCT, and between MPV and MCV. However, there was a significant correlation between PDW and RDW. It seems that the anisocytosis of red blood cells and platelets might co-occur. However, these data are basic observations; further in-depth evaluation of the platelet parameters is recommended.
