Influence of the process of injection on the specific and non-specific signal. The experiments are performed with a sample of IL-6 at 10 ng/mL (for the specific signal) or a buffer solution mL (for the non-specific signal) as described in the Material and Methods.

Mode of injection	Mean raw specific signal (u.a.)	Mean raw non specific signal (u.a.)	Signal to noise ratio (u.a.)
Manual in-tube labelling	1821 ± 334	425 ± 51	4.2
Sequential injection	1634 ± 59	201 ± 31	8.1
