A 40-year-old female asked:

low hemoglobin and high rdw and low mch. is this serious? hemoglobin is 118, rdw is 15.4 and mch is 27.2.

No that low.: High RDW and low MCH are both consistent with blood loss and mild iron deficiency - with menses most likely, or sometimes with an ulcer.
Dr. Craig MacArthur
Pediatric Hematology and Oncology 34 years experience
Probably not: The hemoglobin of 11.8 g/dl is slightly low for a 40 year old female. The RDW is slightly high high and the MCH is low normal. Causes could be mild iron deficiency anemia. These values by themselves are not reason to worry. The context of why they were obtained is important in determining what they mean.

What is hemoglobin a1c?

Dr. Stephen Daquino

Average blood sugar: Hemoglobin A1c is a measure of the percentage of red blood cells permanently bound to glucose. Normally about 5% of our red cells are glycosolated. If you have greater than 6.5% you are diabetic. It is not affected by fasting, and since our rbc's live 90-120 days, it reflects an average over that time.

How accurate is a hemoglobin A1c test in indicating hypoglycemia?

2 doctor answers6 doctors weighed in
Dr. Timothy Ashley
Internal Medicine and Pediatrics 15 years experience
Poor: Hba1c is fair at detecting chronically high bgs, but very poor at detecting low bgs. Fortunately, true low bgs are very rare and almost never sustained or recurrent. The sensation of "hypoglycemia", when related to sugar at all in people not treated with diabetes medications, is usually the normal response to low-ish sugars, which corrects them and keeps the body well.

How long do you have to fast for a hemoglobin A1c test?

Hgb A-1-c: Does not require fasting. It reflects blood sugar control over time. The fast is usually for the blood sugar or lipid profiles drawn at the same time.
