Table 9 Percent recovery of low-concentration and high-concentration plasma spiked with recombinant GFAP

From: Development of a novel, sensitive translational immunoassay to detect plasma glial fibrillary acidic protein (GFAP) after murine traumatic brain injury

Spike concentration (pg/mL) %recovery* (mean ± SD)
  All samples Low-concentration samples (n = 2) High-concentration samples (n = 3)
100 86.3 ± 25.8 67.1 ± 10.5 99.0 ± 25.8
1000 77.5 ± 11.8 73.1 ± 3.1 80.4 ± 15.6
10,000 79.7 ± 13.6 74.1 ± 0.6 83.5 ± 17.8
Mean 81.2 ± 17.3 71.4 ± 6.0 87.7 ± 19.5
  1. *%recovery = ((measured concentration spiked sample-measured concentration neat sample)/concentration of spike) × 100%. SD standard deviation
