How does the cost compare to other LAL methods?
At first glance, it may appear that the cartridges are more expensive than other quantitative LAL methods. Keep in mind, however, that all the reagents needed to run the test – lysate, endotoxin, and LRW – are already included in the cartridge. The standard curve has also been performed already, which typically requires a minimum of 6 wells and 2 additional wells for negative water controls. So one test run with the PTS really includes 8 wells for the curve and 4 wells for the samples and negative controls – a total of 12 wells. The advanced technology of the test also saves considerable time on labor as well.
