The concentration of sodium hyaluronate has been determined in amniotic fluid by a specific radioassay. It shows a large individual variation. The mean concentration is approximately 20 micrograms/ml at Weeks 16-20 of the gestational period. It drops to approximately 1 micrograms/ml at Week 30 and is then constant until the end of the pregnancy.
已通过特定放射测定法测定了羊水中透明质酸钠的浓度。其显示出较大的个体差异。在妊娠期第16 - 20周时，平均浓度约为20微克/毫升。在第30周时降至约1微克/毫升，然后一直保持恒定直至妊娠结束。
