用精确的生物化学和生物学方法来评价月经周期的黄体期必须反复采血以测定孕酮及确定内膜活检时间。每天取血决无可能,而任意采血样又难于准确。因此,只有使用另一种体液,即唾液来作为测定的样本。唾液中的甾体浓度与唾液流速无关,并且一般均能反映血浆甾体的游离部分。本工作使用一种特异和敏感的唾液孕酮放射免疫分析法,比较了同一受试者的唾液及血浆孕酮水平并评价了唾 Precise biochemical and biological methods to assess the luteal phase of the menstrual cycle must be repeatedly taken blood to determine progesterone and determine the time of endometrial biopsy. Blood taken every day is impossible, and arbitrary blood samples are difficult to accurately. Therefore, only another bodily fluid, saliva, is used as the sample for the assay. The concentration of steroid in saliva is independent of saliva flow rate and generally reflects the free fraction of plasma steroids. This work uses a specific and sensitive salivary progesterone radioimmunoassay, the same subjects were compared saliva and plasma progesterone levels and to evaluate the saliva
