Quantification of human serum IgG by turbidimetry and lectin-affinity fluorescent labeling quantification (LAFLQ). Human serum IgG was measured by turbidimetry, and fluorescence intensity was estimated by eqn (1) and compared to LAFLQ measurements.
| Patient | IgG in serum (μg μL−1) | Amount of IgG (μg) | Calculated fluorescence intensity | Measured fluorescence intensity | Difference (%) |
|---|---|---|---|---|---|
| A | 14.0 | 21.0 | 117.3 | 111.3 ± 6.7 | 5.13 |
| B | 13.5 | 20.0 | 114.1 | 118.3 ± 7.6 | 3.51 |
| C | 11.9 | 18.0 | 104.0 | 107.0 ± 4.7 | 2.88 |
