K821135 is an FDA 510(k) clearance for the PREALBUMIN ENZYME IMMUNOASSAY. Classified as Prealbumin, Antigen, Antiserum, Control (product code JZJ), Class I - General Controls.

Submitted by Abbott Laboratories (Abbott Park, US). The FDA issued a Cleared decision on May 5, 1983 after a review of 380 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Hematology FDA review panel, regulated under 21 CFR 866.5060 - the FDA hematology device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Hematology review framework, consistent with the majority of Class II 510(k) submissions.
