do you have the normal ranges for the above tests? every lab has a different range.
your thrombin time is high-normal (most cut-offs are 18.5), if the thrombin time is normal it points towards lupus anticoagulant. however, if the thrombin time was high, it wouldnt be to lupus anticoagulant. your DVVT is elevated, and that could indicate lupus anticoagulant, however, it is not a very specific test and could also indicate other things (or nothing at all). if your physician is concerned that you may have lupus anticoagulant, i would suggest getting a "hexagonal phase phospholipid test". that test is much more sensitive and specific than the DVVT. did you also have the cardiolipin antibody test?

first, is your doctor suspecting lupus anticoagulant in you, and why are you taking coumadin?
aPTT is prolonged in patients with lupus anticoagulant. your PTT is within normal range. the DRVVT and DPT are only slightly elevated, and hence, not specific enough to prove whether or not you have lupus anticoagulant, hence, again, if the doc is suspecting lupus anticoagulant, i would suggest getting a cardiolipin antibody, aPTT, and the hexagonal phase phospholipid test.
i know my answer probably does not shed a lot of light, but unfortunately, the tests your doctor ran are not impressive none conclusive one way or the other. i hope i did help some, however. best of luck!
p.s. i'm heading to bed now, so if you have any further questions, i will be happy to answer them tomorrow!
