Invasive trophoblastic antigen, ITA is a hyperglycosylated form of hCG that is produced by cytotrophoblasts during embryonic implantation and trophoblast invasion of the uterine wall. Prenatal Screening for conditions like Down's syndrome and neural tube defects is done by testing the mother's blood samples for markers including ITA, Alfa feto protine (AFP), dimeric inhibin A (DIA), unconjugated estriol (uE3), etc.
In addition, ITA or HCG is also a tumor marker in gestational trophoblastic diseases, like hydatidiform mole, choriocarcinoma, etc, which are seen during pregancy.
High Serum HCG levels in pediatric blood samples - can be indicators of hepatoblastoma, hepatocellular cancer and infantile liver choriocarcinoma and germ cell tumors.
The low levels of ITA, seen in your daughter, are not of any significance.
