VITROS Chemistry Products LAC Slides on VITROS XT 3400 and VITROS XT 7600 Systems are experiencing an increased occurrence of calibration failure related to lots from coating 0130 and above with Condition Code TH4-63J during calibration, causing the delay of lac test results and potentially impact patient management. The issue was identified by QuidelOrtho through an increase in customer complaints compared to the historical baseline with average failure rate of 1% for coating 0130 in 2025 while average of failure rate for other coating was 0.06% in 2025 and average of failure rate for all coatings is 0.03% for 2024.

Generations 67 and above of VITROS Ca Slides are experiencing an increased occurrence of Condition Code TH4-63J during calibration on VITROS XT 3400 and VITROS XT 7600 Systems, causing calibration failures that delay calcium test results and potentially impact patient management. The imaging reflectometer algorithm detects excessive "spikes" (imperfections) in slide images and generates the TH4-63J condition code when the threshold of 600 spikes is exceeded. Updated analysis revealed a 19-fold increase in failure rates from 0.0043% (2024 baseline) to 0.082% for Generation 67+ slides in 2025, with 100% of calibrator failures occurring at the lowest concentration level. This can result in delayed diagnosis and treatment of conditions such as hypercalcemic crisis, parathyroid disorders, and other calcium-related emergencies requiring urgent intervention.
