Case Study
The patient is a 62 year old Mexican-American male who was seen by his physician for an annual checkup. He had a CBC and comprehensive metabolic panel, lipid panel, ferritin, TIBC, serum iron and % saturation. Results were:
WBC 5.9 x 109/L
Hemoglobin 16.8 g/dL
Hematocrit 49.1%
RBC 5.08 x 1012/L
RDW 12.9
Differential: 47% neutrophils; 39% lymphocytes; 11% monocytes; 2% eosinophils; 1% basophils
Platelet count 176 x 109/L
Comprehensive metabolic panel: within reference range
Cholesterol 202 mg/dL
Serum ferritin: 390 ng/mL (12-282)
TIBC: 292 mg/dL (250-450)
Serum iron 166 mg/dL (35-158)
#1. Calculate the patient’s % iron saturation. Reference range at this facility is 20-50%. Saturation % = serum iron/TIBC
#2. Interpret the patient’s iron status.
#3. What condition is suggested with these results?
#4. The patient was sent to a hematologist who ordered genetic testing. Results showed a single heterozygous mutation at C282Y. There was no evidence of mutation of the H63D or S65C mutation. What do these genetic results mean?
#5. The patient donated a pint of blood every other week for 2 months. The physician ordered a repeat serum ferritin. The result was 218 (23-233). What was the rationale for the periodic phlebotomy? Why did the serum ferritin decrease?
#6. What is the risk of iron overload in the body?
