Is a mean corpuscular volume of 68 fL severe?

A mean corpuscular volume (MCV) of 68 fL alone does not indicate a serious health problem, as it is merely an indicator of red blood cell size. The detailed analysis is as follows:

Mean corpuscular volume is a measure used to evaluate the size of red blood cells and is interpreted together with mean corpuscular hemoglobin concentration (MCHC) and red blood cell count to determine the type of anemia. These three parameters influence each other, and the severity must be assessed by considering all indicators collectively. In healthy adults, the normal MCV range is typically between 80 fL and 100 fL. Values below this range suggest microcytic anemia. The severity of anemia cannot be determined by a single parameter but requires comprehensive evaluation of multiple factors, including the number and quality of red blood cells and the underlying cause of anemia. An isolated MCV value of 68 fL may indicate smaller-than-normal red blood cells, but it does not confirm the type or severity of anemia. Other parameters such as MCHC and red blood cell count must also be evaluated to better assess the extent of anemia. In summary, with an MCV of 68 fL, it is advisable to consult a physician for a comprehensive physical examination and relevant laboratory tests to determine whether anemia or other health issues are present. Through thorough medical evaluation and appropriate management, a more accurate diagnosis and effective treatment plan can be established.

A white blood cell count of 3.44×10⁹/L is slightly below the normal range. It is generally not concerning when caused by bacterial infection, but may be more significant if due to immune system disorders.
