Existing Wording: Variations are detected by comparing a patients genetic sequence with a reference using a variety of techniques each with their own trade-offs in terms of applicability, cost, speed, availability, and precision. Some can only be used for DNA but not RNA or amino acid sequences or can only detect certain types of changes, for example.

Proposed Wording: Variations are detected by comparing a patients genetic sequence with a reference using a variety of techniques. Each of these techniques come with their own trade-offs in terms of applicability, cost, speed, availability, and precision. For example, some techniques can only be used for DNA but not RNA or amino acid sequences. Others can only detect certain types of changes.
