Specimen Type: Serum
Specimen Required: 3-5 Cc Yellow Top Gel Vial
Day Performed: Daily
Reporting Time: 8-24 Hours
Methodology: Beckman Coulter Access II/ Snibe Maglumi 4000
CLINICAL SIGNIFICANCE:
A higher-than-normal ferritin level may be due to:
- Liver disease due to alcohol abuse
- An autoimmune disorder, such as rheumatoid arthritis
- Frequent transfusion of red blood cells
- Too much iron in the body (hemochromatosis)
A lower-than-normal level of ferritin occurs if anemia is caused by low iron levels in the body. This type of anemia may be due to:
- A diet too low in iron
- Heavy bleeding from an injury
- Heavy menstrual bleeding
- Poor absorption of iron from food, medicines, or vitamins
- Bleeding in the esophagus, stomach, or intestines
