What is the interpretation and recommended course of action for a patient with mild anemia and slightly low MCHC (Mean Corpuscular Hemoglobin Concentration)?

From the Guidelines

For a patient with mild anemia and slightly low MCHC, the recommended approach is to first identify the underlying cause through additional testing while initiating iron supplementation, as suggested by the most recent guidelines 1. The patient's laboratory results show a hemoglobin level of 12.6 g/dL, which is below the normal range, indicating anemia. The MCHC is also slightly low at 31.0 g/dL, suggesting hypochromic anemia. According to the guidelines, iron deficiency is the most common cause of hypochromic anemia 1.

• The first step is to confirm iron deficiency through iron studies, including serum ferritin, transferrin saturation, and total iron binding capacity, as recommended by the British Society of Gastroenterology guidelines 1.
• Ferrous sulfate 325 mg once daily, containing approximately 65 mg elemental iron, is typically prescribed to treat iron deficiency anemia, and should be taken on an empty stomach with vitamin C to enhance absorption.
• A complete blood count with reticulocyte count, iron studies, and peripheral blood smear should be ordered to determine the specific type of anemia and to monitor response to treatment.
• Potential causes of iron deficiency, such as blood loss, poor dietary intake, or malabsorption, should be investigated, and patients should be counseled about iron-rich foods and potential supplement side effects.
• Follow-up testing in 4-6 weeks is essential to monitor response to treatment, with hemoglobin typically improving by 1-2 g/dL per month with effective therapy, as suggested by the guidelines 1.

From the FDA Drug Label

Purpose Iron Supplement Therapy Ferrous Sulphate is an iron supplement for iron deficiency and iron deficiency anemia when the need for such therapy has been determined by a physician.

The patient's lab results show mild anemia (Hemoglobin: 12.6 g/dL, which is below the normal range of 13.0-17.7 g/dL) and slightly low MCHC (Mean Corpuscular Hemoglobin Concentration: 31.0 g/dL, which is below the normal range of 31.5-35.7 g/dL).

• The patient's iron levels are not directly provided, but the low MCHC and mild anemia suggest possible iron deficiency.
• The recommended course of action would be to consult a physician to determine the need for iron supplement therapy, such as ferrous sulphate 2.
• Iron supplementation may be necessary to treat the iron deficiency and anemia.

From the Research

Interpretation of Lab Results

• The patient's hemoglobin level is 12.6 g/dL, which is slightly below the normal range of 13.0-17.7 g/dL, indicating mild anemia 3.
• The Mean Corpuscular Hemoglobin Concentration (MCHC) is 31.0 g/dL, which is slightly below the normal range of 31.5-35.7 g/dL 4.
• The patient's platelet count is 201 x10E3/uL, which is within the normal range of 150-450 x10E3/uL.
• The white blood cell count (WBC) is 3.6 x10E3/uL, which is within the normal range of 3.4-10.8 x10E3/uL.

Recommended Course of Action

• Further testing is recommended to determine the underlying cause of the mild anemia and low MCHC, such as iron deficiency or vitamin B12 deficiency 5.
• The patient's platelet count and WBC count are within normal ranges, but the MCHC and hemoglobin levels suggest a possible deficiency in iron or vitamin B12.
• A PLT/MCH ratio can be calculated to help differentiate between pure iron deficiency anemia and combined iron and vitamin B12 deficiency, with a ratio of >12.00 suggesting a possible combined deficiency 5.

Additional Considerations

• The patient's red blood cell count (RBC) is 4.51 x10E6/uL, which is within the normal range of 4.14-5.80 x10E6/uL.
• The patient's hematocrit is 40.6%, which is within the normal range of 37.5-51.0%.
• The patient's mean corpuscular volume (MCV) is 90 fL, which is within the normal range of 79-97 fL.
• The patient's neutrophil, lymphocyte, monocyte, eosinophil, and basophil counts are all within normal ranges or not established.
