Autoimmune and Infectious Disease Testing

PhD lx System

Versatile IFA and EIA processing system for autoimmune and infectious disease testing all on one open platform.

We recently purchased the PhD lx for our lab and are impressed by how simple it is to run our IFA assays. It's easy to train laboratory personnel to operate, and the maintenance is straightforward. We like the flexibility that the system offers to run both Bio-Rad and third-party assays. This allows us to automate a broader test menu and helps aid in meeting the testing needs of our patient population.
