Ferritin Elisa Test Kit
INTENDED USE
The Ferritin assay is an enzyme-linked immunosorbent assay (ELISA for the in vitro quantitative determination of ferritin in human serum. This assay is useful in diagnosis and screening of anemia. For professional use only.
Summary
Ferritin is a macromolecule with a molecular weight of at least 440 kD (depending on the iron content) and consists of a protein shell (apoferritin) of 24 subunits and an iron core containing an average of approx. 2500 Fe3+ ions (in liver and spleen ferritin).1 In humans, it acts as a buffer against iron deficiency and iron overload.2 If the ferritin level is low, there is a risk for lack of iron, which could lead to anemia or iron deficiency without anemia. In the setting of anemia, low serum ferritin is the most specific lab finding for iron-deficiency anemia.3 Low ferritin may also indicate hypothyroidism, vitamin C deficiency or celiac disease. Low serum ferritin levels are seen in some patients with restless legs syndrome, not necessarily related to anemia, but perhaps due to low iron stores short of anemia.4,5 A normal ferritin blood level, referred to as the reference interval is determined by many testing laboratories. The ranges for ferritin can vary between laboratories but typical ranges would be between 30–300 ng/mL (=µg/L) for males, and 30–160 ng/mL (=µg/L) for females. A value less than 50 is considered as iron deficiency. Serum ferritin levels are measured in medical laboratories as part of the iron studies workup for iron-deficiency anemia.6 The ferritin levels measured usually have a direct correlation with the total amount of iron stored in the body.
Test principle
Sandwich principle. Total duration of assay: 80 minutes.
• Sample, Anti-Ferritin coated microwells and enzyme labeled Anti-Ferritin are combined.
• During the incubation, ferritin presents in the sample is allowed to react simultaneously with the two antibodies, resulting in the ferritin molecules being sandwiched between the solid phase and enzyme-linked antibodies.
• After washing, a complex is generated between the solid phase, the Ferritin within the sample and enzyme-linked antibodies by immunological reactions.
• Substrate solution is then added and catalyzed by this complex, resulting in a chromogenic reaction. The resulting chromogenic reaction is measured as absorbance.
• The absorbance is proportional to the amount of ferritin in the sample.
Precautions and warnings
• For in vitro diagnostic use only. For professional use only.
• All products that contain human serum or plasma have been found to be non
reactive for HBsAg, HCV and HIVI/II. But all products should be reared as
potential biohazards in use and for disposal.
• Mix the sample in the wells thoroughly by shaking and eliminate the bubbles.
• Conduct the assay away from bad ambient conditions. e.g. ambient air
containing high concentration corrosive gas such as sodium hypochlorite acid,
alkaline, acetaldehyde and so on, or containing dust.
• Wash the wells completely. Each well must be fully injected with wash solution.
The strength of injection, however, is not supposed to be too intense to avoid
overflow. In each wash cycle, dry the liquids in each well. Strike the microplate
onto absorbent paper to remove residual water droplets. It is recommended to
wash the microplate with an automated microplate strip washer.
• Failure to remove adhering solution adequately in the aspiration or decantation
wash step(s) may result in poor replication and spurious results.
• Do not use reagents beyond the labeled expiry date.
• Do not mix or use components from kits with different batch codes.
• If more than one plate is used, it is recommended to repeat the calibration
curve.
• It is important that the time of reaction in each well is held constant to achieve
reproducible results.
• Ensure that the bottom of the plate is clean and dry.
• Ensure that no bubbles are present on the surface of the liquid before reading
the plate.
• The substrate and stop solution should be added in the same sequence to
eliminate any time deviation during reaction.

Specimen collection and preparation
• Human serum is recommended for this assay.
• Cap and store the samples at 18-25 ℃ for no more than 8 hours. Stable for 7 days at 2-8℃, and 1 month at -20℃. Freeze only once.
• Do not use heat-inactivated samples.
• Sediments and suspended solids in samples may interfere with the test result which should be removed by centrifugation. Ensure that complete clot formation in serum samples has taken place prior to centrifugation.
• Avoid grossly hemolytic, lipemic or turbid samples.
