Abstract: Methods, devices, systems and kits for obtaining blood samples are provided. Devices include a cuff, a pressure source, and a timing mechanism. Devices may further include one or more of a: warming mechanism, lancing mechanism; automated sample collection device, automated sample analysis device, and communication unit. Systems include such a device, and may include sample collection, sample analysis, or communication devices.
Methods include placing a cuff on a digit of a subject, inflating the cuff, and obtaining a small volume blood sample. Methods may further include warming a digit; lancing a digit; pulsing the cuff; and providing a signal indicating the end of the sample collection time period.
Kits may include a device, a sample collection vessel, and may include a disposable for use in sample collection.
These methods, devices, systems and kits for obtaining blood samples may be used to easily, reliably, and consistently obtain blood samples from subjects.

Abstract: Devices, methods and systems are provided for reducing the sample volume required for analysis. Inserts placed within a sample container, and substitute sample containers having smaller volume sample chambers are provided. Methods are provided for detection and quantification of target substances in reduced volume samples. Methods include placing a small-volume of sample in a small-volume insert. Methods include diluting a small-volume sample, and placing the diluted sample in a small-volume insert. Methods include reducing the volume of sample, and: increasing illumination; increasing dye concentration or amount; increasing the amount of an enzyme substrate; increasing the amounts, concentration, or labeling of antibodies for detection; increasing optical detector sensitivity; increasing the path length of light passing through the sample; decreasing the separation between sample and detector; altering the wavelength, or polarization, or number of wavelengths, passing through the sample; increasing electronic amplification of electrical signals; altering assay temperature; and other alterations.
