Test Protocol
ODB is the sensitive protocol for determination of low optical density up to OD 10 in the starting phase of a fermentation.
If the optical density is expected to be higher than OD 10, then protocol ODD should be used (same protocol with preset 1:30 predilution step).

Calibration:
No test specific calibration is required for the OD test. The factory-made calibration of the photometer unit of Cedex Bio Instruments is stable and highly equivalent between the instruments.

Quality control:
Control OD Level 1 Bio (CONO1, 114)
Control OD Level 2 Bio (CONO2, 115)
Control OD Level 3 Bio (CONO3, 116)

Use the recommended control material. Other suitable control material can be used in addition.

The optical density of microbial suspensions can be determined in following ranges:

• ODB: 0.1 to 10 OD
• ODD: 3 to 360 OD

Precision
Representative performance data on Cedex Bio Analyzers are shown. Results obtained in individual laboratories may differ.
Precision was determined in samples of three concentration levels. Coefficients of variation (CV) were calculated for in-run precision (n=21) and inter-run precision (on 10 days).

Mean OD	2	20	150
CV in-run	0.7%	1.0%	1.0%
