- 
                        The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5 % within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

                                            Protocol
- This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Tetrahydrofolic Acid (THFA) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Tetrahydrofolic Acid (THFA) and unlabeled Tetrahydrofolic Acid (THFA) (Standards or samples) with the pre-coated antibody specific to Tetrahydrofolic Acid (THFA). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Tetrahydrofolic Acid (THFA) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Tetrahydrofolic Acid (THFA) in the sample.

                                            Assay Precision
- 
                        Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Tetrahydrofolic Acid (THFA) were tested 20 times on one plate, respectively
 Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Tetrahydrofolic Acid (THFA) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100
 Intra-Assay: CV<10%
 Inter-Assay: CV<12%

                                            Handling Advice
- The Stop Solution is acidic. Do not allow to contact skin or eyes. Calibrators, controls and specimen samples should be assayed in duplicate. Once the procedure has been started, all steps should be completed without interruption.
