Abstract

See full text

An automated method for preparing a sample suspension. The sample suspension can be used for both MALDI and antimicrobial susceptibility (AST). A suspension is prepared, and a portion of that suspension is removed for a first analysis (e.g. MALDI), leaving a remaining volume. The turbidity of the remaining volume is measured. If the turbidity is below a first threshold, the suspension is not used for a second analysis (e.g. AST) and is subjected to a concentration protocol to raise the turbidity of the suspension. If the turbidity is within a predetermined range, a volume of the suspension is calculated that will deliver a predetermined amount of sample to a vessel for the second analysis. If the turbidity of the suspension is above the predetermined range, and the suspension has not been diluted a predetermined number of times, the suspension is diluted according to a dilution protocol.
