Dr. Mark Holodniy

Mar 12, 2005

Dear Dr. Holodniy,

I found that HBV DNA result can be expressed in IU/mL or ng/mL, so could you tell me the conversion factor between the 2 systems?

Many thanks

Response from Dr. Holodniy

1 IU = about 5 copies or genome equivalents. 1 pg = about 280,000 copies 1 ng = 1000 pg 1 ng = 2.8 x 10(8) copies 1 ng = about 5 x 10(7) IU

cd count raised from 19 to340 and fallen to 175
HTLV +/need for further testing?
