Methamphetamine Testing

Total House Inspections offer two services for testing methamphetamine in houses.  For both services, we use an independent laboratory that is IANZ accredited to analyse the samples collected and the sample methods are taken in strict accordance with NIOSH 9111.


Lab Composite Test

A Lab Composite Test gives you, the client, the best value for money to check your property for peace of mind.  Using a laboratory supplied testing kit, an individual sample is taken from each key area or location throughout the house where meth is commonly found.  The samples are then labelled, packaged up and sent to an approved laboratory where they take small amounts from each of the sample tubes and analyses them as a combined/composite sample.  The results of the composite sample will then be calculated to give an average level reading that is measured against the Ministry of Health (MoH) Guideline level.  If over the MoH guideline level then an Individual / Discreet Lab sample is needed to be completed for each area. 


Because individual samples have already been taken from each area there is no need for us to come back to your property.  If it is within 30 days from the initial samples being received by the laboratory, they can re-test these samples as individual tests to determine what areas exceed the MoH Guideline level and what areas are under.  Once you know where the contamination problem is in your property you can target that area, potentially reducing your decontamination costs.


Individual / Discrete Lab Tests

If you suspect Methamphetamine is going to be present in your property or the Laboratory Composite test exceeds the Ministry of Health Guideline level, then an Individual / Discrete Lab Test is recommended.  This type of testing requires an individual sample to be taken from each area using a laboratory supplied testing kit and for each of those samples to be tested individually in the laboratory.  The results from the laboratory will give an exact reading for each sample taken and identify which are over and which are under the MoH Guideline Level.
