The matrices

Blood is the most commonly used biological fluid for clinical laboratory testing.  With some exceptions, most of the protein assays offered by Diagam can be performed in both serum and plasma.  Other matrices often used for testing include urine, cerebrospinal fluid (CSF), fecal matter, etc.

The different Diagam matrices are chosen according to the assay to be performed.  Indeed, although most analytes are found in all biological fluids, they differ in their physical and chemical properties.  It is therefore important to use a specific method depending on the matrix used.
