The HL-FRT Rapid Test Device (Whole Blood/Serum/Plasma) is a highly sensitive immunoassay for semiquantitative determination of human ferritin in whole blood, Serum or Plasma. This test is intended for professional use as an aid in the diagnosis of diseases haemochromatosis, inflammation, liver disease, and certain types of cancer, e.g. breast cancer. The sensitivity of the test is 200 ng/ml.
Principle of FRTRapid Test Device
The HL-Ferritin Rapid Test Device (Whole Blood/Serum/Plasma) detects ferritin through visual interpretation of color development on the internal strip. Ferritin antibodies are immobilized on the test region of the membrane. During testing, the specimen reacts with ferritin antibodies conjugated to colored particles and precoated onto the conjugated pad of the test. The mixture then migrates through the membrane by capillary action, and interacts with reagents on the membrane. If there are sufficient ferritin in the specimen, a colored band will form at the test region of the membrane. A test band (T) singal weaker than the reference band (R) indicates that the ferritin level in the specimen is between 200-400 ng/mL. A test band (T) signal equal or close to the reference band (R) indicates that the ferritin level in the specimen is approximately 400 ng/mL. The appearance of a colored band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
