I had my 1st. PE at 18 and by the time I was 25 I'd had 5 PE's and several DVT. No hospital or hematologist has ever been able to regulate me on a anticoagulant. My materinal grandmother had a clot at 35 and it killed her. My mother had her 1st at 50 and had a total of 5.
I know about bad labs. My recent (10/12/12) labs were:
Thrombin-Antithrombin (TAT) Complex was 17.1
Proteine C Activity was 167%
Anti-thronbin lllActivity was 124%
ANA Screen was positive
I have had luck sicking myself with lovenox. My very best to you
