|---|---|---|---|
| Maternal age at delivery (years) | 31(21–39)3 | 31 (23–40)3 | NS |
| Total IgE in third trimester (kU/l)2 | 107 (7–1327)3 | 10 (2–211)3 | P < 0·001 |
| Total IgE 2 years after delivery (kU/l)2 | 89* (7–1197)3 | 10 (2–327)3 | P < 0·001 |

The diagnosis of allergy was based on the women's own statement of allergic disease confirmed with a positive SPT (ALK, Copenhagen, Denmark) result.
2
Total serum IgE levels were analysed with Pharmacia CAP System IgE FEIA (Pharmacia & Upjohn Diagnostics AB). The detection limit was > 2 kU/l.
