H.6 investigation summary: material: 275005.Batch: 2013911.Satisfactory results when retention samples were tested for performance using three (3) sera panel numbers of each reactivity: serum no.12: control, returned goods and retention, showed reactive results at 1:1 to 1:4 and reactive minimal at 1:8.Serum no's; 17 ¿ 20 : control, retuned good and retention showed reactive results at 1:1 and reactive minimal at 1:4.Serum no¿s.26, 36 and 40 : control, returned good and retention sample showed reactive minimal results at 1:1.Serum no's.8, 9 and 10: all lots showed negative results.Visual inspection was performed to retention samples and returned goods received, no discrepancy were found.Normal particle size was observed.Dhr batch history records were reviewed with satisfactory results, no deviations were reported.In-process and qc testing were within specification batch record review do not show any discrepancy.One photo received from customer showed normal particle size.Complaint unconfirmed based of retention sample, returned goods test results, batch history record review and photo evaluation.Special attention should be provided to: antigen storage and use.Sample and room temperature during the test.Type of specimen used: collection and preparation.According of the ¿manual of test for syphilis¿ edition 9.0 the following ¿sources of error¿ had been identified for increase of reactivity or false reactivity for the rpr test.If the time of rotation is too long, test reactivity may be increased.If the card is excessively rotated and tilted (to and fro motions) by hand after removal from the rotator, a false reactive result may occur.If the serum is unevenly spread in the circle, the antigen and the antibody may not mix properly.A cross functional team continually monitors all product complaints for trends and determines if any additional actions are necessary beyond the current investigation process.
