# 91.17 Postponing a laboratory service.

If the scientist determines that it is not possible to accurately analyze or make a laboratory determination of a sample immediately after receipt because standard materials, laboratory equipment and supplies need replacement, or for any other substantial reason, the scientist may postpone laboratory service for such period as may be necessary.
