Screening as a first measure is a legitimate method of providing information before a more comprehensive detailed laboratory analysis is undertaken. Screening techniques are used within laboratories as a cost and time saving measure and there is no reason to rule screening out as part of the forensic testing of property for the presence of methamphetamine residues.
Screening usually involves swabbing of areas then using the resulting sample to produce a rapid test result similar to a pregnancy test. There are a number of these kinds of tests available, some specifically designed for property meth testing and some are more general in design.
The screening tests we use have been developed specifically for us and have been independently checked both in the field and in a laboratory. We know that when one of our tests provides a positive result, any corresponding laboratory sample will confirm that result.
The major advantages in having a professional conduct screening tests for you are:
- Lower cost per test – we can sample multiple areas within a property at a fraction of the cost of a full set of laboratory samples
- The buffer solutions are non-corrosive so cause no damage to walls – laboratory swabs are soaked in alcohol so can and often do remove paint and surface coatings.
- Results are extremely fast – within a few hours rather than a few days you can make a decision to attend an auction or not.
- Screening tests are extremely reliable – we always say that it’s not the test that is unreliable, it’s the tester. We’ve seen many people misusing lab tests over years so rather choose a professional than a self-styled expert. Anyone can put on a set of purple gloves, that doesn’t make them proficient in their job.
Talk to your local Residue Testing NZ tester about your needs. A preliminary screening test is both cost effective and quick. Of course all our people are trained in laboratory sampling techniques also so should that be necessary we can help there too.
