Remarks

Lab Staff:
SPECIMEN SOURCE IS REQUIRED

• Indicate source of calculi: bladder, kidney, prostatic, renal, or urinary.
• If multiple stones are collected and individual testing is desired for each stone, place each stone into its own container. Testing must be ordered separately on each stone. Each order will be charged separately.
• Important: Any specimen received with residual moisture on the stone or in the container will result in a testing delay. STNPC will be performed and billed as appropriate:
**A dry stone will not stick to the walls of the container
**Do not send stone in formalin, surgical gel, or any other liquid as it interferes with the analytical procedure.
**Do not tape specimen to anything – tape interferes with the analytical procedure.
**Do not place stone directly in a bag. If specimen is received in a bag, either transfer stone into a screw-capped, plastic container or place bag containing stone in a screw-capped, plastic container.
**Do not send filter.
