Liver biopsy procedure and indications

Abstract

Liver biopsy sampling and subsequent analysis for mineral content can be a valuable diagnostic tool for micronutrient associated illness in cattle. Although there may be some ap­prehension when using the blind technique, the procedure has little risk of adverse consequences. Utilizing proper biopsy site preparation and appropriate landmarks reduces risk of compli­cations while optimizing the probability of obtaining a sample large enough for micronutrient evaluation. Liver samples are appropriate for evaluating toxicity associated with cobalt, cop­per, manganese, selenium and zinc and deficiency associated with copper, manganese, selenium and zinc.
