A method of inspecting the state and the performance of point-of-care biological test appliances (i = 10 to 14) for on-site implementation using a portable inspection appliance, namely, on the spot of said point-of-care biological test appliances, away from a medical analysis laboratory, the method comprising the steps of: a) on-site inputting or reception of qualitative data (QLD[i]) characterizing a point-of-care biological test appliance ( i) for inspection and characterizing the environment in which the appliance is to be found, said qualification data comprising identification and location of said point-of-care biological appliance as well as data selected from at least data relative to the state, maintenance, frequency, of use, and method of use the point-of-care appliances, and the state of products and consumables and/or of so-called control solution for the use of said point-of-care biological test appliance; b) on-site inputting or reception of the value (QTD[i]) of a biological variable of said "control" solution as measured by the point-of-care biological test appliance (i) for inspection; c) acquiring the value (QTD[i]) of the biological variable of the control solution as measured by a reference biological test appliance; d) transmitting the input or received value (QTD[i]), the acquired value (QTD CTL), and the input or received qualitative data (QLD[i]) to a centralizing computer system; e) within the centralizing computer system, determining a bias (B[i]) that is to be expected between the input or received value (QTD[i]) of the biological variable and the value (QTD CTL) as measured by the reference appliance, the expected bias being determined as a function of the input or received qualitative data (QLD[i]), including data relating to the environment in which the appliance is used, and of comparison data stored in the computer system; f) comparing the value (QTD[i]) as measured by the point-of-care biological test appliance with the value (QTD CTL) as measured by the reference appliance while taking the bias (B[i]) into account; g) storing comparison data relating to the comparison performed in the computer system, said comparison data being stored in association with the qualitative data; h) within the computer system, generating a inspection report (C-R); and i) sending the report (C-R) to the inspection appliance (2, 3') or to a computer terminal associated with the inspection appliance (2, 3'). a) on-site inputting or reception of qualitative data (QLD[i]) characterizing a point-of-care biological test appliance ( i) for inspection and characterizing the environment in which the appliance is to be found, said qualification data comprising identification and location of said point-of-care biological appliance as well as data selected from at least data relative to the state, maintenance, frequency, of use, and method of use the point-of-care appliances, and the state of products and consumables and/or of so-called control solution for the use of said point-of-care biological test appliance; b) on-site inputting or reception of the value (QTD[i]) of a biological variable of said "control" solution as measured by the point-of-care biological test appliance (i) for inspection; c) acquiring the value (QTD[i]) of the biological variable of the control solution as measured by a reference biological test appliance; d) transmitting the input or received value (QTD[i]), the acquired value (QTD CTL), and the input or received qualitative data (QLD[i]) to a centralizing computer system; e) within the centralizing computer system, determining a bias (B[i]) that is to be expected between the input or received value (QTD[i]) of the biological variable and the value (QTD CTL) as measured by the reference appliance, the expected bias being determined as a function of the input or received qualitative data (QLD[i]), including data relating to the environment in which the appliance is used, and of comparison data stored in the computer system; f) comparing the value (QTD[i]) as measured by the point-of-care biological test appliance with the value (QTD CTL) as measured by the reference appliance while taking the bias (B[i]) into account; g) storing comparison data relating to the comparison performed in the computer system, said comparison data being stored in association with the qualitative data; h) within the computer system, generating a inspection report (C-R); and i) sending the report (C-R) to the inspection appliance (2, 3') or to a computer terminal associated with the inspection appliance (2, 3').
