Iron, serum
fS-Fe KL 2566
Serum iron concentrations decrease in association with inflammatory states, absorption disorders, and malnutrition. Conversely, high concentrations can be related to factors such as excessive use of iron preparations, iron poisoning, and various anemia conditions.
Indications
Suspected iron poisoning. When suspecting mild iron deficiency, ferritin or transferrin testing is recommended in addition to serum iron.
Sample
Collect 1 mL of fasting serum, with a minimum of 0.5 mL. A cloudy, hemolytic, or icteric sample is not valid. It is important to take the sample in the morning (between 7-9 am) due to the diurnal variation of iron levels. Hemolysis can lead to falsely increased iron values.
Storage and delivery
Delivery at room temperature, if it arrives within 24 hours. Can be stored refrigerated over the weekend.

Photometric, accredited method.
Turnaround time
1 – 2 weekdays
