I don't know if anyone is interested but if u have to go up to hospital to get ur ana blood done for ur on warfarin and would prefer to phone ur own count in I have a coag u check machine with new lancets and slides all sealed. Of course u will have to start getting these from ur own dr. The machines are normally 600-800 pound but selling mine for 250. It's saved me going to the hospital for so long as u just ring through ur inr they tel u wat to take. It's exactly the one they use to test u.
