No other clinical signs reported, and other than mild conjunctivitis clinical exam was unremarkable.

The symptoms sound like hypothyroidism but the low T4 could be due to concurrent disease and you would expect a mild anaemia not the opposite. I think you need to wait for your TSH and repeat PCV before anything else. Do you have any biochemistry and WBC count?</p><div style="clear:both;"></div>
