Methods for obtaining a sample from a subject include providing a sample collection room within a retail store; and obtaining a sample from the subject. Sample collection rooms may include one or more of a warming table; a warming plate; a fingertip warmer; an air-warmer; a reclining chair; a calming feature; and adjustable lighting. Samples may be analyzed at the retail location or sent to elsewhere for analysis. Sample collection rooms may house a sample analysis device or system. Samples may be small, e.g., a finger-stick, and may be analyzed in a short period of time, e.g., in less than five hours, or less than four hours.
