Up to ten sites at a property are tested using one kit. Any detected level of methamphetamine is a cumulative level of all the sites tested at the property. A minimum of one swab per 10m2 in any one room is taken.

If the level of methamphetamine detected is less than or equal to 1.5ug then no further testing is required.

If the level is above 1.5ug, further testing, (MDSL Aliquot or MDSL Comprehensive) is recommended, as it may be that the contamination could be restricted to one room or area.

The MDSL Composite test is ideal if you are confident that you will not have methamphetamine contamination in the property, or very low level contamination only, It will not identify levels from individual rooms – if the composite is high, further testing will be required to do that and will probably be requested by the company engaged to remediate the property.

Composite testing is essentially a screening test, backed by assurance that scientific analysis provides, as opposed to field testing kits.

It is cheapest testing option provided by MDSL, but if levels are high, further testing ( and costs) could be recommended/necessary.

Individual samples are taken from each room. They are grouped together in sets of no more than five samples. A small sample ( or aliquot) is taken from each sample in a set and analysed. If the level from the aliquot is sufficiently low then no further testing of the samples in that group is required. However, if the level is high, each sample will then need to be individually tested.

This testing may be less expensive than the MDSL Comprehensive testing, potentially significantly less expensive).
MDSL Aliquot testing will NEVER be more expensive than the Comprehensive testing.

Individual samples are taken from each room and sent for individual analysis.

Samples are taken from each wall/ceiling in the room and analysed together. The result is the average for the number of samples taken in the room. This provides a sample for the entire room and gives a reliable result for the entire room, rather than just one sample location in the room.

This is the option that will give the most complete analysis of methamphetamine contamination in a property and will help to provide any remediation company with compiling a plan for the decontamination of the property.

It will however be the most expensive testing procedure.
