The transition in between tests that evaluate precisely the same entity (e.g., LAL cascade) might be created by evaluating the two tests to verify the equivalence of the new method. [22]  The comparison of your Restrict of detection and inhibition/enhancement is elementary. The sensitivity of the new process is usually evaluated on spiked products more info samples.
