Abstract: Provided are systems and methods for preserving a cervico-vaginal fluid sample.

Abstract: Provided herein are compositions comprising populations of cells obtained from a pregnant subject comprising at least one of a Hofbauer cell, a cytotrophoblast, a syncytiotrophoblast, an extravillous trophoblast, a villous core stroma, or a fetal vascular cell; a stabilization buffer, wherein the stabilization buffer comprises a preservative; and a cellulosic collection device, wherein at least a subset of the population of cells are intact and inviable and methods of making and using such compositions.

Abstract: Provided herein are methods for detecting a menstrual cycle disorder. Menstrual cycle disorders is detected through analysis of a property of a collected menstrual fluid sample, such as gene expression, flow rate, protein content, nucleic acid content, biomarkers, or other properties.

Abstract: Samples, systems for collecting samples, and methods of preserving samples from menstrual fluid are provided.

Abstract: A medical kit for analysis of vaginal biological samples includes a sample collector, an extractor, and an assay cartridge. The sample collector is compressible and insertable in a vaginal canal for collecting biological samples, and includes a cup-shaped head configured to cradle a cervical os. The extractor includes a sample receptacle configured to receive the sample collector via an open end. The extractor includes a compression mechanism with a compression element that is movable inwards into the open end of the sample receptacle to apply a compression force in response to activation of a release element. The extractor further includes a reservoir in fluid communication with the sample receptacle, the reservoir receiving the biological samples from the sample collector in response to the compression force being applied within the sample receptacle. The assay cartridge has a docking mechanism configured to fluidly communicate with the reservoir of the extractor.
