Controls and standards for assays and method for manufacturing the controls and standards is described. The controls or standards comprise a porous carrier material which has quantitatively reversibly absorbed and dried thereon an analyte for the control or standard wherein the analyte is not degraded over time while it is absorbed to the porous carrier material. Preferably, the controls and standards are provided as a control strip () in which the porous carrier material () is adhered to the distal end () of a support member (). To quantitatively elute the analyte from the carrier to a solvent for an assay, the carrier is contacted to the same solvent used for the samples in the assay. After the analyte has been eluted, the carrier is discarded and the assay is performed. The controls and standards are useful for assays which detect bacteria, fungi, viruses, and proteins.
