1 doctor agrees

In brief: One sample at a time

A blood sample is spun down and the white cells are separated into at least 3 tissue culture media sets.
An amnio sample is spun down, the cells resuspended and divided into three tissue culture sets. Of primary importance: only one sample is ever set up at a time. No other sample is near another until the cultures have been completely set up and labeled. That prevents mixing up two babies by mistake
