Hepcidin Research Use Only (RUO) Test Information

Is the Hepcidin test patented and FDA approved?

Yes. The Intrinsic LifeSciences laboratory developed Hepcidin test and tracer are patented
(Patent # 7,723,063 and 7,745,162).
Currently the hepcidin assay is not FDA approved. However, it has been validated in several peer-reviewed studies and is marketed as a Research Use Only assay. It is offered for academic, clinical, government and pharmaceutical customers, worldwide.

Can I use this test for patient samples?

No, this is an RUO test. To order our diagnostic test, the Intrinsic Hepcidin IDxTM Test, please go to IntrinsicDx - Order Tests / Specimen Collection & Shipping Instructions.

What is the principle of the Hepcidin test?

Hepcidin is measured in plasma, serum, urine and other body fluids using a patented tracer and a competitive enzyme-linked immunosorbent assay (ELISA).

What is the stability of Hepcidin?

In serum and plasma, hepcidin is stable for at least 6 years when samples are stored either at -80°C or -20°C. In urine, hepcidin is stable for 6 months at -80°C.

How are Hepcidin results reported?

Hepcidin concentrations can be reported as either nM or ng/ml. To convert between the two units use the following calculations:  1 nM = 2.789 ng/ml or 1 ng/ml = 0.358 nM.

What body fluids has hepcidin been found in?

Hepcidin could be present in virtually any body fluid. To date we have measured hepcidin in plasma, serum, urine, saliva, cerebral spinal fluid, cord blood, amniotic fluid and peritoneal dialysis fluid.

Sample Collection for Hepcidin Research Use Only (RUO) Testing

How should samples be collected for the Hepcidin RUO testing?

Serum samples: Collect blood from fasting subjects in a red top or yellow top serum collection tube. Immediately after blood collection, place the tubes upright in a rack and allow blood to clot at room temperature for 30 minutes to 2 hours. Centrifuge the tubes at 1500xg for 15 minutes and collect supernatant.


Plasma samples: Collect blood from fasting subjects in a tube containing either lithium heparin or EDTA (purple top). Invert tubes several times immediately after collection and place horizontally on a platform rocker at moderate speed for 30 minutes to 2 hours at room temperature. Centrifuge the tubes at 1500xg for 15 minutes and collect supernatant.

Transfer 0.25 ml into a clean 0.5 to 2.0 ml cryogenic vial and store frozen until shipment. Smaller sample volumes can be accepted upon request, particularly for infant and pediatric studies.


Urine: collect first morning urine at mid-stream and transfer 0.25 ml into a clean 0.5 to 2.0 ml cryogenic vial and store frozen until shipment.

How should samples be stored before testing?

After collection, store serum, plasma and urine samples at -80°C (or at -20oC) until shipment. Do not freeze whole blood. Always transfer serum or plasma to another vial before freezing.

What types of samples are unacceptable for testing?

-samples stored at room temperature (15-30oC) for longer than 24 hours.

-samples that thawed during transport.

-samples that are largely hemolyzed.

-samples that have been insufficiently clotted.

Shipping Information

How should samples be packed?

Place sample vials in a primary receptacle (e.g. a cardboard cryogenic storage box), which should be placed in a secondary package (such as zip lock bag) that includes absorbent material. If leakage occurs during transport, the absorbent material will contain the spill. Place secondary container into the rigid outer package such as an insulated, leak-proof, thermal shipping container and fill the container with dry ice. Please use sufficient amount of dry ice to allow for a 2 day transit time, in case of a delivery delay.

Finally, please include the sample manifest (list of samples) with each shipment.

How should samples be shipped?

Ship samples by Priority Overnight delivery. Always consult national and international regulations for the safe shipment of biological substances on dry ice. We routinely receive international shipments from World Courier and FedEx.

Please ship on Monday-Thursday. Our office is closed on weekends and during US national holidays. Contact your preferred carrier for additional shipment instructions and schedules.
