Asking for my 27 year old female daughter cbc results rbc 4.89, hemoglobin 10.9, hematocrit 35.3, mvc 72.2, mch 22.3, mchc 30.9, rdw 16.1 iron deficiency?

Yes, these CBC results are compatible with iron deficiency, but fairly mild. She should ask her doctor about testing for blood iron level and perhaps to consider treatment.

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. Talk to the doctor who ordered the tests. Having said that, iron deficiency anemia is a likely explanation. It is common in women. She may take oral iron and multivitamin supplements to correct iron due to menstruation. Wish you good health!
