    Brady – This is excellent, although a little complicated with so much on one slide – We always use Roman numerals for coag factors, so that 5a & 8a should be corrected – I’m not sure what you mean when you say that the PTT reflects primarily Factor XI since it will detect significant deficiencies in any of the Factors that it includes – Anyway, very nice job – I’m proud of you – Dennis

    Need to make it just one step more complex and add Lovenox effect; probably on your lower left area, that is fairly empty, Mainly affecting factor X on a 4:1 basis over heparin, with minimal effects on thrombin and other factors.
