What does it mean when the MCV is normal and RDW is low and what does it mean when the grf is 87?

What does it mean when the MCV is normal and RDW is low and what does it mean when the grf is 87?

Nothing.: Mcv is red cell size. Rdw is the variation in red cell size. A low RDW has no meaning. Gfr is a way of measuring kidney function, and a GFR over 60 is of no concern. ...Read more

MCH is high (39.8pg) MCHC is high (376g/l) and RDW is low (10%) - MCV is normal (90.6fL) - what could this mean?

MCH is high (39.8pg) MCHC is high (376g/l) and RDW is low (10%) - MCV is normal (90.6fL) - what could this mean?

More info: Is there a family history of spherocytosis? Is there any history of jaundice (yellowness) or of enlarged spleen. Why was this group of tests done and what other tests were done? Looking forward to more info. ...Read more

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, if you were to provide the actual values if may be possible to render an opinion. ...Read more

Spherocytosis?: Are you anemic? Was a reticulocyte count done? What's the big picture? Labs mean nothing without it. If you're very close to your lab's reference range, it may mean nothing -- a few % of healthies fall outside. A low RDW would be a bit of a surprise in classic spherocytosis. ...Read more

What could cause low MCV and high RDW but normal MCH, hemoglobin, and hematocrit for over a year?

What could cause low MCV and high RDW but normal MCH, hemoglobin, and hematocrit for over a year?

How low?: Reference ranges are set so that several percent of healthy folks fall outside on either end. If your peripheral smear is unremarkable and the MCV above 70, I'd forget the whole thing. My RDW is always high from donating blood. There are some variants of thalassemia minor that will produce this and puzzle people over a lifetime, though MCH is usually lowish. ...Read more

What does having low HB, HCT, MCV, MCH, MCHC & high RDW but normal RBC & ferritin mean? HB 10(11.2-14.1) RBC 4.15(3.85-5.02) Ferritin 5.7(4.6-204)

Need iron: It means you have an iron deficiency leading to anemia. It could be not enough iron in your diet to replace menstrual losses but you should check with your doctor to be sure and to receive a recommendation for treatment. ...Read more

RDW (high) 18.3, MCV (low) 73.9, MCH (low) 23.8, ferritin (normal) 83. Possible conditions or reasons for this? Lymphocytes 0.9.

RDW (high) 18.3, MCV (low) 73.9,  MCH (low) 23.8, ferritin (normal) 83. Possible conditions or reasons for this? Lymphocytes 0.9.

. Iron deficiency: I assume you are newly anemic, and this is not congenital. Low MCV, and high RDW are seen in iron def, but the normal ferritin complicates things. Anemia of chronic disorders also looks like this, but with high ferritin (and low TIBC). Normal ferritin is suspicious for a mix of iron def. and chronic disorders anemia. These findings are never normal and need further evaluation. ...Read more

Need evaluation: All lab results need to be evaluated in the clinical context and the doctor who ordered the test is usually in the best position to do that. It would also help to have the actual results of iron studies. Iron deficiency is a common cause of microcytic hypochromia. Mild thalassemia being another one. If your results are improving, recovery from iron deficiency is a likely explanation. ...Read more
