Have you ever been asked if a specimen has been placed in formalin or saline but you are reluctant to have a sniff and blast your mucous membranes?. Here is a simple test ; Add few drops of the fluid to 1 ml of your reticulin silver solution. If it turns white the fluid is saline. If it turns black you have got formalin . Easy! David Grehan .
