International Proficiency Testing Scheme for the Leptospirosis MAT

The International Proficiency Testing Scheme for the Leptospirosis MAT is a collaborative project provided by laboratories in Amsterdam, Melbourne and the United Kingdom, on behalf of ILS.

The objectives of the scheme are (a) to provide participants with information about the quality of their MAT testing, as an aid to improved performance, and (b) to encourage a general improvement in the performance of MAT testing and in leptospirosis diagnosis throughout the world.

Panels of 5 samples have been sent to participants approximately annually since 2002. After all results are received, participants receive an emailed preliminary report, identifying the samples. Later they receive a final report, comparing and analysing results from different laboratories.


Any laboratory performing the MAT may participate in the scheme. Approximately 100 laboratories from about 45 countries participate.

Non-commercial laboratories from countries classed by World Bank as Low Income or Lower-Middle Income will automatically qualify for the concession. Specific individual requests for the concessional rate from laboratories in countries in the Upper Middle Income group that are undergoing hardship will be considered. A list of the World Bank classifications can be found HERE.

Round 15 is expected to be delivered in February 2018 and Round 16 in February 2019.

Laboratories wishing to participate in Round 15 should contact Roderick Chappel at by Friday 16 February. Laboratories wishing to participate should nominate the currency in which they wish to pay.
