2. Stability of WB spots under different storage conditions.
Stability of WB spots under different storage conditions. Individual points represent the total of six measurements on samples dried and stored in sealed bags at 4°C (▴, ⧫), room temperature (#, •), and 37°C (*, ▪). These were stored with dessicant (▴, #, *) and without dessicant (⧫, •, ▪).

3. Relationship between L-ferritin values determined on serum and on dried blood spots (paper).
Relationship between L-ferritin values determined on serum and on dried blood spots (paper). Interrupted line is the line of identity. Correlation coefficient is significant (r = .723,P < .001).

4. Relationship between measurements of transferrin receptor performed on serum and on dried blood spots (paper).
Relationship between measurements of transferrin receptor performed on serum and on dried blood spots (paper). Interrupted line represents the line of identity. Correlation is highly significant (r = .968, P < .001).

5. Values of (A) dried paper samples of blood L-ferritin and (B) serum L-ferritin.
Values of (A) dried paper samples of blood L-ferritin and (B) serum L-ferritin. Values are shown separately for normal subjects (N), subjects with ID, and subjects with IDA.
