In particular, the systems and methods ensure that only instruments that pass a quality assurance protocol are used for point-of-care testing. ## Claims ### Claim 1 A computer implemented method, comprising: transmitting a request for instrument calibration verification from a data manager to two or more instruments based on a predetermined schedule; in response to receiving the request for the instrument calibration verification, performing by the two or more instruments the instrument calibration verification according to the request for instrument calibration verification and using: (i) a predetermined number and type of calibration fluids and a predetermined number of sample testing cartridges of a set of sample testing cartridges, or (ii) an electronic simulator, to generate calibration verification data; transmitting the calibration verification data from the two or more instruments to the data manager; based on whether the calibration verification data is within range of predetermined calibration target values, determining at the data manager a compliance status for each of the two or more instruments as either compliant or non-compliant; storing at the data manager the determined compliance status for each of the two or more instruments in a data table, the data table comprising: (i) identification information associated with instruments of the two or more instruments, and (ii) the compliance status for each of the two or more instruments; transmitting the data table from the data manager to the two or more instruments; and enabling use of a first instrument from the two or more instruments for performing one or more analytical tests on a first biological sample when the compliance status for the first instrument stored in the data table indicates the first instrument from the two or more instruments is in compliance; or at least partially disabling use of a second instrument from the two or more instruments for performing the one or more analytical tests on a second biological sample when the compliance status for the second instrument stored in the data table indicates the second instrument from the two or more instruments is not in compliance. ### Claim 2 (depends on 1) The method of claim 1, wherein the one or more analytical tests are configured to detect one or more analytes selected from the group consisting of: sodium, potassium, chloride, total carbon dioxide, ionized calcium, glucose, blood urea nitrogen (BUN), creatinine, lactate, hematocrit, pH, partial pressure of carbon dioxide, partial pressure of oxygen, troponin I, troponin T, creatine kinase MB, procalcitonin, beta human chorionic gonadotropin (bHCG), human chorionic gonadotropin (HCG), N-terminus of a prohormone brain natriuretic peptide (NTproBNP), prohormone brain natriuretic peptide (proBNP), brain natriuretic peptide (BNP), myoglobin, parathyroid hormone, d-dimer, neutrophil gelatinase-associated lipocalin (NGAL), galectin-3, and prostate specific antigen (PSA). ### Claim 3 (depends on 1) The method of claim 1, wherein the predetermined number of calibration fluids is one to five. ### Claim 4 (depends on 1) The method of claim 1, wherein the predetermined number of the sample testing cartridges of the set of sample testing cartridges is one to five. ### Claim 5 (depends on 1) The method of claim 1, wherein the two or more instruments are all connected to one another in a wireless network. ### Claim 6 (depends on 1) The method of claim 1, wherein the two or more instruments are a subset of instruments of a plurality of instruments, and the plurality of instruments are all connected to one another in a wireless network. ### Claim 7 (depends on 1) The method of claim 1, wherein the predetermined schedule comprises a scheduled time for the instrument calibration verification, and the method further comprises generating, for each of the two or more instruments, the predetermined schedule comprising the scheduled time for the instrument calibration verification before said transmitting the request for the instrument calibration verification in accordance with the predetermined schedule. ### Claim 8 (depends on 7) The method of claim 7, further comprising: resetting the scheduled time for the instrument calibration verification when the determined compliance status for each of the two or more instruments indicate that one or more instruments from the two or more instruments is/are in compliance. ### Claim 9 (depends on 1) The method of claim 1, further comprising: sending a request for one or more replacement instruments when the determined compliance status for each of the two or more instruments indicate that one or more instruments from the two or more instruments is/are not in compliance. ### Claim 10 (depends on 1) The method of claim 1, further comprising: sending a request for maintenance of one or more instruments from the two or more instruments when the determined compliance status for each of the two or more instruments indicate that one or more instruments from the two or more instruments is/are not in compliance. ### Claim 11 (depends on 1) The method of claim 1, further comprising: displaying the request for the instrument calibration verification on a display screen of each of the two or more instruments. ### Claim 12 (depends on 1) The method of claim 1, wherein the electronic simulator to be used for the performance of an instrument calibration verification for an instrument from the two or more instruments is internal to the instrument. ### Claim 13 (depends on 1) The method of claim 1, wherein the electronic simulator is a separate computing device from the two or more instruments, and in communication with each of the two or more instruments.
