Depending on the methods used to analyse micropollutants, differences in results are observed. AGLAE studies them and presents them in the test reports. These observations help laboratories to better interpret their analysis results.
AGLAE has published several studies on organic pollutants studies on organic pollutants based on test observations:

• Method differences for organic micropollutants in clean water
• Reliability of the determination of chloroacetamide metabolites

AGLAE proficiency tests are used not only to assess laboratory performance, but also to check their estimated measurement uncertainties and to assess the repeatability and reproducibility of their measurements.
AGLAE provides personalised reports to laboratories, enabling them to focus on possible improvements to their analyses.

AGLAE can also improve the quality of your measurements:

• Organic pollutants in wastewater
• Base parameters and indicators in water
• Metals in water 
• Indexes in water

They are carried out as part of self-monitoring or regulatory controls. These tests cover some of the requirements of :

• accreditation scope of biological analyses of aquatic media (check AGLAE's accreditation Cofrac No. 1-1664)
• approvals issued by Ministries of Health to carry out sampling and analysis for water quality control purposes 
• approvals issued by Ministries for the Environment to carry out analyses in the field of water and aquatic environments
• the Water Framework Directive (WFD 2000/60/EC), which sets objectives for preserving aquatic ecosystems

• habitation of running waters
• plant effluent water
• sampling from running water
• water intended for human consumption

• Determination of the faunal list of macro-invertebrates
• Determination of the floristic list of diatoms
• "Daphnia" test: determination of the inhibition of the mobility of Daphnia magna Straus - acute toxicity test
• Quantification of Giardia cysts and Cryptosporidium oocysts

• Macro-invertebrates in running waters: laboratories that have observed unusual taxa will be able to obtain a second expertise, which will enable them to take better account of their unique profile.
• Diatom biology index: photographic prints of 10 remarkable species will be attached to the test report. The assessment of several technicians is possible.
• Ecotoxicology: tests on fresh and waste water and the test to determine the inhibitory effect of water samples on the luminescence of Vibrio fischeri (or "Microtox" test) can be carried out on the samples.
• Protozoans: evaluation of partial and complete analysis (with resuspension in tap water) and enumeration of 'total' and 'healthy' protozoans.

AGLAE can also improve the quality of your measurements:

• water microbiology
• water for medical use

They are carried out as part of self-inspection or regulatory controls. These proficiency tests cover some of the requirements:

• accreditation scope of  microbiological analyses applied to pharmaceutical products and cosmetics (check AGLAE's accreditation No. 1-1664)
• regulatory framework linked to marketing authorisations for cosmetic products: it is necessary that microbiological analysis providers and the cosmetics industry inter-calibrate in order to achieve comparability of measurement results.

AGLAE manufactures and dispatches cosmetic products such as creams and lotions suitable for microbiological testing of cosmetics.
Preservatives are used in order to

• check the effectiveness of the neutralising agent for the challenge test
• check the applicability of the method (neutralisation of the preservative/verification of the effectiveness of the neutraliser) for enumeration and detection tests

• Challenge test: antimicrobial efficacy tests to assess the antimicrobial protection of cosmetic products.  Laboratories determine reduction rates in accordance with ISO 11930 'Cosmetics - Microbiology - Evaluation of the antimicrobial protection of a cosmetic product' or by using their in-house analytical procedures.
• Enumeration of aerobic mesophilic bacteria and yeasts/moulds: according to ISO 21149 or 16212 respectively or equivalent method.
• Detection of specified micro-organisms: Escherichia coli, Candida albicans, Staphylococcus aureus and Pseudomonas aeruginosa according to ISO standards 21150, 18416, 22718 or 22717 respectively or equivalent method.

• AGLAE provides 'challenge test in cosmetics' interlaboratory comparisons under accreditation.
• Since its creation, AGLAE has specialised in interlaboratory tests on microbiological analyses and, since 2016, on cosmetics. 
• AGLAE provides an assessment of the individual performance of each laboratory, as well as an assessment of the dispersion of results across the profession, with a view to estimating measurement uncertainty and identifying areas for improvement (assessment of the effect of practices and media suppliers).

AGLAE also provides microbiological analysis service providers the opportunity to improve the quality of their measurements:
- water microbiology
- water for medical use
- bacteriology - microscopic examination - wet mount and Gram stain (see details in "Medical biology")
See all AGLAE's tests

They are carried out as part of self-monitoring or regulatory controls. These tests cover some of the requirements of :

• Accreditation purposes (see Accreditation No. 1-1664)

• pharmaceutical and cosmetic quality water
• water used in healthcare establishments (purified and highly purified water)
• water for haemodialysis, dialysates, endoscope control solutions

Depending on the type of water, the service providers quantify in particular : 

• bacterial endotoxins
• Pseudomonas aeruginosa
• yeasts
• culturable micro-organisms
• non-tuberculous bacteria

• The waters used are representative of those encountered by laboratories in their routine analyses.
• AGLAE's proficiency tests are used to assess laboratory performance and also to estimate the repeatability and reproducibility of their measurements. Their measurement uncertainties are checked for the measurement of endotoxins and an estimate of their measurement uncertainties is provided for some microbiological parameters.
• AGLAE provides personalised reports to laboratories, enabling them to focus on possible improvements to their analyses.

AGLAE can also improve the quality of your measurements in the following areas:
