Ortho-Clinical Diagnostics Inc. (OCD) has received complaints of weakened reactivity or false negative reactions for the positive controls when using these lots. Preliminary findings have shown that the source of saline and/or container used when performing the Indirect Antiglobulin Test using Anti-S can affect assay results. If you experience the weaken reactivity or false negative reactions with the positive control in your laboratory, you should consider using an alternate source of saline.
When the positive control does not perform as expected, the test is considered invalid and test results cannot be interpreted. OCD is not aware of any reported erroneous results related to this issue.
Effective immediately, OCD requires that you follow the Supplemental Test Procedure to continue using all in-date and future lots of Blood Grouping Reagent Anti-S.
