Method of processing a sample

A method of processing a sample in a receptacle having one or more assay order states, the method comprising the steps of:

• collecting the sample within the receptacle, wherein the receptacle comprises a label, and wherein the label comprises:
• a plurality of discrete areas having known associations with multiple assays, each of the plurality of discrete areas having a known association with one assay of the multiple assays, and each of the plurality of discrete areas being configured to be altered from a first assay order state to a second assay order state, wherein for each of the plurality of discrete areas:
• the first assay order state is defined by a removable label covering machine-readable indicia in the discrete area, the first assay order state indicating that the one assay having the known association with the discrete area is not to be performed,
• the second assay order state is defined by exposure of the machine-readable indicia in the discrete area, the second assay order state indicating that the one assay having the known association with the discrete area is to be performed,
• a plurality of assay-identifying indicia, each assay-identifying indicia indicating the one assay having the known association with the corresponding discrete area of the plurality of discrete areas, and each assay-identifying indicia including alphanumeric characters or graphical symbols, and
• patient-identifying indicia;
• and
• altering at least one discrete area of the plurality of discrete areas from the first assay order state to the second assay order state by removing the corresponding removable label, thereby exposing the machine-readable indicia associated with the at least one discrete area.
