Medical Laboratory Assistants (MLAs) prepare, and in some cases process samples within a pathology laboratory. They also utilise pre-analytical systems in order for biomedical scientists (BMS) or Medical Laboratory Scientific Officers to process the biochemical tests requested on the sample. The majority of an MLA's time is spent in processing specimens. As such, the MLA has to have excellent knowledge of their particular sample acceptance policy, whilst obeying the data protection act, patient confidentiality, COSHH and the Caldicott rules.
A typical method of sample acceptance (in a clinical chemistry lab) is as follows:
MLA's also deal with all sample queries and give low level advice to cinical staff on sample acceptance and correct sampling method. They may also do minor upkeep on the pre-analytical systems as well as further upkeep on some point of care analysers — depending on the laboratory in which they are based.
