Healthy women's immune cells mapped for future disease research
NCT ID NCT05609799
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at the different types of immune cells in the blood of 40 healthy Danish women aged 18-41. The goal was to create a reference for normal immune cell levels in women of reproductive age. This information will help future studies understand how the immune system affects diseases in this group.

Inclusion Criteria: * \- Healthy women of fertile age (18-41 years) with a regular menstrual cycle (22-35 days) who are in the luteal phase of their menstrual cycle at the time collecting the blood sample (day 20 to 28 of cycle and serum progesterone \> 20 nmol/l at the day of blood sample). The group should consist of an approximately 1:1 ratio of women with ≥1 previous liveborn child and women with no previous pregnancy. Exclusion Criteria: * \< 18 years old or \>41 years old * History of ≥1 known pregnancy loss including both spontaneous and missed abortions. An induced abortion is accepted if it was performed more than 2 years before study participation. * Pregnancy within last 6 months * Treatment with drugs acting on the immune system or hormonal contraceptive drugs either acting systemically or locally (intrauterine device releasing progesterone). * Known disease with influence on the immune system and/or endocrine system * Previously received a blood transfusion
