Bacteriology - Microscopic examination in neutral solution: wet mount and Gram stain

image banniére
EQA in medical biology

Description of the programme

These interlaboratory comparisons (AGLAE's programme ‘117’) address any laboratory carrying out microbiological analyses (medical biology laboratories, hospital laboratories, testing laboratories...).

Characteristics of these EQA:

  • Neutral solution containing a strain for microscopic examination (wet mount and Gram stain)
  • Possibility to self‐evaluate several technicians using the results file (provision of a sheet dedicated to your performance calculation).
  • On-line data entry


List of parameters

Détail des paramètres mis en oeuvre

Morphology, cell arrangement, mobility and Gram stain

Qualitative assessment of the morphology, cell arrangement, mobility and of the result of the Gram stain (Gram positive / negative)

Of interest to biomedical laboratories: an overview of the reported therapeutic orientations (bacterial type / antibiotic therapy) will be provided in the test report

The  microscopic examination is also possible in blood : Bacteriology - Microscopic examination in blood - Wet mount and Gram stain
