Analysis of spiked human serum samples using the MCP-1 immunosensor

Human Serum Samples (1/10 dilution)*
Spiked concentrations (pg/mL) Measured concentrations (pg/mL) Recovery (%) RSD (%)
13 5.31 ± 3.66 40.8 28.2
30 15.58 ± 4.83 51.9 16.1
71.8 67.57 ± 6.95 94.1 9.7
100 94.90 ± 17.18 94.9 17.2

The non-spike serum sample was used as reference.

The parameters were extracted from the four-parameter equation used to fit the standard curve. The measured concentrations were obtained after subtract the native MCP-1 concentration in the serum samples (5.6 pg/mL, 1/10 dilution).
