Appendix E

Instructions for Programming a
New Assay

This appendix provides two examples of assay kit instructions and

step-by-step directions for programming each assay. The appendix

includes two sample assays: one with a ratio transformation

calculation and a POS/NEG cutoff determination, and another with a

standard curve.These examples are based on real assays; however,

the results have not been verified on any clinical kits. The kit

instructions are provided so that users can see how it is possible to

translate the kit wording into an ELx800 assay program. For clarity,

only the user menu choices from the reader screens are shown.

Refer to

Chapter 3

for details.

Important!

The ELx800 user is responsible for

programming the reader properly according to their
specific kit instructions, and for verifying that the
calculations are performed correctly.
