Can reagents from other manufacturers be used with the InSure® test cards?
Absolutely not. The InSure® assay is a patented formula and will not work with different reagents and buffers manufactured by other companies. Additionally, InSure® FIT™ test cards can only be developed at Quest Diagnostics laboratories and cannot be interchanged with the conjugate and buffer used for developing the InSure® Quik F I T™ test cards in-office.
