Screening Assessment

For peace of mind

ASSESSMENT TYPES

Field Composite

In a Field Composite multiple samples are taken at a property and then combined into a single test tube on site and sent to the laboratory for analysis. The results are reported as an accumulative total.

Advantages:
- One sample taken in every “high use” area in accordance with NZS8510:2017
- As only minimal test tubes are used the cost of analysis is more affordable

Disadvantages:
- As the samples are combined into a test tube, if contamination is found we are unable to isolate which room holds the contamination.

Laboratory Composite

In a Laboratory Composite multiple samples are taken at a property and they are all stored individually. The laboratory will take an extraction from each test tube and combine them into a single analysis. The result are reported as an accumulative total.

Advantages:
- One sample taken in every “high use” area in accordance with NZS8510:2017
- As the samples are all kept separate, if contamination is found they can be re-analysed individually to ascertain which sampling location holds the contamination.
Note: Re-analysis is an additional cost per test tube

Disadvantages:
- As samples are taken and kept individually, the sample collection takes longer and stricter cross-contamination practices must be enforced which increases the cost.
