Amniotic fluid β2 microglobulin (β2-m) levels were measured by radioimmunoassay in 78 pregnant women between the 14th and the 42nd week of gestation. 62 were healthy subjects, while eight were affected by EPH gestosis, seven by diabetes (cl. B-F) associated with Rh immunization in one case, one by hydramnios. There was no significant correlations either between β2-m and creatinine (n=18), or between β2-m and lecithin sphyngomyelin ratio (L/S) (n=16), although low concentrations of β2-m were usually observed after the 35th week of gestation. It is noteworthy that only in one case out of seven with amniotic levels <5μg/ml the L/S ratio was <2.

Abstract
Amniotic fluid β2 microglobulin (β2-m) levels were measured by radioimmunoassay in 78 pregnant women between the 14th and the 42nd week of gestation. 62 were healthy subjects, while eight were affected by EPH gestosis, seven by diabetes (cl. B-F) associated with Rh immunization in one case, one by hydramnios. There was no significant correlations either between β2-m and creatinine (n=18), or between β2-m and lecithin sphyngomyelin ratio (L/S) (n=16), although low concentrations of β2-m were usually observed after the 35th week of gestation. It is noteworthy that only in one case out of seven with amniotic levels <5μg/ml the L/S ratio was <2.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
