Table 2 Estimates of times (in years) for recoveries of antibodies in desiccated blood spots

From: Dried blood spots as a source of anti-malarial antibodies for epidemiological studies

  Time (years) for original value to fall to :
T (°C) 80% 90% 95%
-20°C 9.0 4.2 2.1
4°C 1.1 0.5 0.2
10°C 0.65 0.31 0.15
15°C 0.44 0.21 0.10
20°C 0.30 0.14 0.07
25°C 0.21 0.10 0.05
30°C 0.15 0.07 0.03
  1. Extrapolated times for total anti-MSP-119 IgG to fall to a given percentage of initial concentration in desiccated blood spots on 3 MM paper at different temperatures.
