Is any of this happening?
Be seen today
Contact your care team promptly if you have a diagnosed dyscrasia and develop new bleeding, fever, increasing breathlessness, rapidly worsening weakness, or symptoms that differ from your usual pattern.
Fever or feeling suddenly unwell needs prompt assessment if you have been told that your infection-fighting white cells are very low.

Does any of this apply?
Book an appointment
Arrange a routine medical appointment for unexplained tiredness, repeated infections, new easy bruising, frequent nosebleeds, unusually heavy menstrual bleeding, or persistent small red or purple spots on the skin.
These symptoms often have causes other than a dyscrasia, but they may justify an examination and blood test.
Every sign above is quoted from the sofidex article on Dyscrasias. If you are not sure, err upward — it is always reasonable to be checked.
