Unconjugated Estriol and Freezing

I am currently involved in a study called THE ASSESSMENT OF MATERNAL SERUM
MARKERS IN EARLY PREGNANCY. We are looking at the triple screen, a
prenatal diagnosis test that gives risk factors for aneuploidies and neural
tube defects by looking at maternal serum levels of alpha-fetoprotein
(msAFP), beta human chorionic gonadotropin (BhCG), and unconjugated estriol
One of the possible problems with keeping serum samples is that
*supposedly* uE3 levels can change (I have heard it increased) after being
frozen and thawed repeatedly. I would like to do a side study seeing the
possible changes in uE3 levels after freezing and thawing serum samples.
Can anyone tell me where I could find information (biochemical, general
OB/GYN, etc.) on uncongujated estriol with the freezing effects.
Supposedly, there is/are paper(s) on this subject already, but my previous
searhces have come up nil.
If you know where I could look or if you have a bibliography of these
papers, and if you could tell me, that would be greatly appreciated.
