Yes, you can be treated if you have a protein deficiency (e.g. protein S or protein C) – this shouldn’t pose any problems. The consultant will go through a blood clot risk assessment with you during a consultation to assess if you would require Clexane after treatment, which is used to prevent a blood clot from occurring.
