The doctor tested the Ommaya reservoir Thursday and Friday. He inserted a dose of isotope (i.e. radioactive fluid) and then had a scanner take pictures to track the flow through Andrea's body at 3 3-hour intervals on Thursday and 2 3-hour intervals on Friday. Needless to say, it made the day drag out long. Next step is radiation for the rest November.
Andrea is strong and we all are encouraged by your prayers.
