Correlation of oestriol levels in saliva, plasma and urine of pregnant women.
Unconjugated and total oestriol (E3) have been determined in saliva (S) and plasma (P) by radioimmunoassay using a highly specific antiserum against E3. Total oestrogens (E = E1 + E2 + E3) in urine were analysed by the Kober-Ittrich method. No correlation (P greater than 0.05) was found between unconjugated E3 (S) and total E (U) as well as total E3 (S) and total E (U). Total E3 (S) and unconjugated E3 (P), total E3 (S) and total E3 (P) correlated weakly (P less than 0.05 and greater than 0.01). The six remaining correlations were highly significant (P less than 0.001 or less than 0.0001).
