thiobarbituric acid assay 
Method of assessing the amount one or more end products of lipid peroxidation, the oxidative degradation of lipids, in a solution using an assay in which thiobarbituric acid is heated with a tissue or biological fluid sample at an acidic pH to produce a red chromogen. The level of TBA-reactive substances in the sample is determined by spectrophotometric analysis of absorbtion at ~532 nm or fluorescence at 553 nm.

Synonyms
Related Synonyms: TBA assay ;   TBA test ;   TBARS assay ;   lipid peroxide analysis using the thiobarbituric acid assay with spectrophotometric readout
Definition Sources: PMID:36810
