Introduction
Mean corpuscular volume (MCV) is 76.5 fL, which is generally considered abnormal, indicating that the red blood cells are smaller than normal. If this is due to sideroblastic anemia, treatment under a doctor's guidance with oral vitamin B6 and pyridoxine hydrochloride tablets may be necessary. During medication, it is advisable to consume more blood-nourishing foods such as pork liver and donkey-hide gelatin (Ajiao).
An average red blood cell volume of 76.5 fL is generally considered abnormal, indicating that the red blood cells are smaller than normal.
The normal range for red blood cell volume is 80–100 fL. A value of 76.5 fL falls below this range and suggests microcytosis (smaller-than-normal red blood cells). This condition is commonly caused by iron deficiency. In contrast, enlarged red blood cells (macrocytosis) are typically due to vitamin B12 deficiency. When abnormalities in red blood cell size are detected, it is important to promptly visit a hospital for trace element testing and, under medical guidance, supplement iron or vitamin B12 as needed. Microcytosis is usually caused by conditions such as iron-deficiency anemia or sideroblastic anemia. Common symptoms include general fatigue, dizziness, vertigo, and palpitations. If the cause is iron-deficiency anemia, treatment under a doctor's supervision may include oral medications such as dextran iron dispersible tablets, compound ferrous sulfate granules, or ferrous fumarate capsules. If the cause is sideroblastic anemia, treatment may involve taking vitamin B6 or pyridoxine hydrochloride tablets as directed by a physician.
In addition, during medication, it is beneficial to consume more blood-nourishing foods, such as pork liver, donkey-hide gelatin (Ajiao), etc.
