The present invention provides a dry solid medium with a visible tracer useful in the collection and tracking of biological materials in a form suitable for storage and subsequent analysis. In particular, the invention provides a dry solid medium with an inert visible material which, upon contact with a biological sample, indicates the area of the dry solid medium occupied by the sample. The invention also provides a dry solid medium including additional components which function in subsequent analysis of biological materials using, for example, PCR, reverse transcriptase initiated PCR, LCR, RFLP, or genetic hybridization. The invention further provides methods for using the dry solid medium of the invention. |
