The unqualified item was negative coincidence rate. In exploratory study, only 11 batches (68.8%) complied with industry standard. The unqualified items were negative coincidence rate, detection limit and repeatability.</p><p><b>CONCLUSION</b>At present, rubella virus IgM diagnostic Kits have some quality problems in the market.
