Hello. Good night doc. I want to ask, yesterday after performing GCU, all blood was normal, except for the MCH MCV, the MCHC got a low number, and the RDW was high. Based on the results of the lab, what examination will I do next? Until now there are no complaints, it’s just that I have rhinitis. Thanks.
Hello, thank you for the question to HealthReplies.com
First of all, you need to know that in order to interpret the results of a laboratory examination, in addition to having to list your symptoms, you also need to list all the results of the examination (your examination results, including normal ones), units, and your laboratory normal values. MCH, MCV, MCHC, and RDW cannot be interpreted without knowing your Hb / erythrocyte / hematocrit value.
In general, low MCH, MCV, and MCHC indicate that you have small (microcytic) red blood cells and low Hb in each of your (hypochromic) red blood cells. Most likely you actually have anemia (your Hb / erythrocyte is low), but if your Hb / erythrocyte examination is normal, chances are you have hemoconcentration (for example because you are vomiting / diarrhea, or you drink less). It is better to bring the results back to the doctor who recommends an examination for a more complete interpretation of the results.
Hypochromic microcytic anemia itself has a variety of causes, but the most common cause is iron deficiency anemia. Other possible causes of hypochromic microcytic anemia are lead toxicity, chronic disease, thalassemia, and hemoglobin abnormalities.
I hope that I have enough information to answer
