Class II — the FDA judged the product may cause temporary or medically reversible harm, with a remote chance of serious harm.
This is the FDA's risk judgment for this recall. It describes the potential of the product as a category — it does not establish that any specific unit harmed anyone. Most recalls are Class II or III.
Chemistry Products LAC Slides. Catalog Number: 8433880. 1 Sales Unit = contains 5 cartridges of 60 slides, for a total of 300 tests.
Why it was recalled
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.
Is your unit affected?
The recall covers only the specific lots or serial numbers the FDA listed. Enter the lot or serial number from your product's label and we'll check it against that list.
A match means your unit may be covered — stop and call your pharmacist before doing anything. No match suggests it isn't covered, but confirm anyway: code formats vary and lists can be incomplete. Your unit not being listed does not guarantee it is safe, and being listed does not mean you have been harmed.

What this is — and is not
A recall is a recorded FDA enforcement action — the FDA logged that a firm is removing or correcting a product. It does not establish that any specific unit harmed anyone, and causation is not established by a recall. The class above is the FDA's risk judgment for the product category, not a finding about your unit. This page informs and compares; it is not medical advice and never tells you to start or stop a drug or device.
