The Immunoblot is highly specific in detecting whether an antibody response exists against a particular pathogen.
The Immunoblot is composed of blot strips upon which separate single antigens of the pathogens are affixed. These are capable of binding antibodies (lgG and lgM respectively) and are dyed via chemical reaction for easy visualisation. The stripe normally also contains VisE (a surface marker), which has a high level of sensitivity to the organism.
Material: 1 x Serum tubes (centrifuge after blood drawing)
Turnaround time: Two days (Note: Taking into account the required pre- and post-analytical work, the report is created in about one week)
