What is a Quantitative GMO Test?

A quantitative test determines the amount of GM DNA in the sample provided for testing. This test is offered after samples test positive for GM ingredients in the qualitative test or can be used as the primary testing method if requested. This service has wide applicability, for example, current EU regulations state the value of 1% as the maximum tolerance level after which a marketable food item is required to be labeled GM. Therefore, a sample testing positive in a qualitative test may need to undergo further quantitative tests to determine whether the GM content reaches the tolerance level set by the GMO regulations of a particular country.

We use state-of-the-art real-time PCR equipment (based on a TaqMan technology); to conduct our quantitative GM tests.

Two specific tests are offered:

1. Amount of Transgenic DNA as a percentage of the total transgenic DNA / total sample DNA.
2. Amount of Transgenic DNA as a percentage of the total transgenic DNA / total DNA of specific ingredient, e.g. Roundup Ready DNA / total soy DNA.

The usual turnaround time for quantitative tests is 5-7 working days. Special arrangements can be made for a shorter turnaround time.
