For standard nematode testing, there are two types of samples, depending upon when they are collected and their intended purpose.

1. Predictive: preseason samples taken to predict potentially harmful nematode populations in the crop to be planted.
2. Diagnostic: samples taken during the growing season to diagnose suspected nematode problems in the current crop.
