• The code identifies the observation or test, not the actual result.

Key facts

• Lawsonia intracellularis Ab/Negative control in Serum by Immunoassay
• Lawsonia intracellularis Ab/Negative control
• The result of this test can be read by a microplate photometer where the optical density (OD) is measured at 450 nm. The mean OD values for each of the controls and samples are then calculated followed by a calculation of the percent inhibition (PI) values for the positive control and samples.
