A method for providing laboratory test results to a subject, comprising: A) receiving by a laboratory associated computer system (LACS) a request from a subject for a laboratory test, wherein the laboratory test is to be performed with a biological sample from the subject, and wherein the request from the subject for a laboratory test is associated with no information relating to the identity of the subject, or no more than three pieces of such information; B) providing by the LACS an identifier code to the subject in response to the request, wherein the identifier code comprises or is linked to information regarding the laboratory test to be performed with the sample from the subject; providing a vessel to the subject for sample collection, wherein the said vessel is provided to the user with an identifier having the identifier code or a related code already on the said vessel when the vessel is received by the user; C) obtaining at a sample processing device said vessel containing the biological sample from the subject, wherein the said vessel is associated with the identifier code or a related code; D) processing the biological sample on the sample processing device according to the laboratory test requested by the subject, wherein the sample processing device is in communication with the LACS and wherein information related to the sample is transmitted to the LACS; wherein the said vessel is handled by a laboratory technician during at least one of step C) or D) and wherein the sample processing device uses a cartridge that contains reagents to multiple tests, so that a laboratory technician does not know which subset of tests were actually performed, and E) providing by the LACS results from the laboratory test to the subject, wherein the results from the laboratory test are provided to the subject after the subject provides the identifier code or a related code to the LACS.
