H/o oral cancer prescription in nov, 13, chemo& radiation for 6 weeks. 3 weeks later diagnosed with dvt& pe.on warfarin, esr-100 and crp-4.5 tive please explain?

ESR ; CRP: Esr ; CRP are markers of "inflammation". They can be elevated in pe or dvt. They tend to be elevated in many conditions ranging from pneumonia to rheumatoid arthritis. Certain medications can make them elevated too. Labs such as ESR ; CRP should only be interpreted with rest of the clinical picture and not in isolation.

Ignore them: Malignancies are often associated with increased risk of blood clotting for a variety of reasons. Reduced oral intake, dehydration, and hemoconcentration likely contribute to yours. Esr and CRP are non-specific indicators of inflammation from any source. You have a known source(blood clots). The tests add no additional information or prognostic value. You're treatment with warfarin is correct.

Non specific tests: If you are concerned about ESR and crp, i would advise you to ignore them as these two tests are not very useful to make any diagnosis, so they are too non specific to lay a finger on the cause. Certainly recent cancer diagnosis and treatments can cause test abnormalities like you have. I would advise not checking them again as they can only cause unnecessary anxiety.
