This invention provides devices and methods for sample collection. Devices can include (a) a container having an opening and adapted to receive a liquid sample through the opening; (b) a cover configured to reversibly seal the opening; and (c) a capture device configured to be introduced into the container, wherein the capture device is configured to selectively bind cells of a first type and not to substantially bind cells of a second cell type. The sample can be analyzed to make a measure of telomere abundance and the abundance can be correlated to a measure of health. |
