What is the detection limit for low concentration? And what kind of sample size do you need.

Answer

The Cedex Bio Analyzers provide selectable test protocols for automated IgG determination with high sensitivity down to 10 mg/L and up to 8 g/L. Using the instruments on-board capability for further pre-dilution of the sample, the range can be extended to 40 g/L (when taking advantage of this feature, checking the validity of the results for your individual sample matrix is recommended).

The IgG assay requires only 2-25 µL of sample (for sensitive or high range). A 100 µL sample volume is sufficient to perform the IgG assay and also additional assays from the test menu, such as: glucose, lactate, glutamine, LDH, NH3, etc.
