Aaaaaaghhhhh!

The local GPs' surgery has just called to make an appointment for a repeat blood test. I had one done on Tuesday last and my GP told me that she wouldn't contact me unless there was something to discuss. I'm not particularly concerned as there are a number of non medical reasons why a repeat test might be necessary (lost sample, inconclusive results, errors of various sorts etc) but there is a certain black humour in having blood taken on Friday 13th. The woman who spoke to me did offer an appointment 'very early in the morning' but I opted for one in the middle of the day, just to be safe.
