¹In GEq of microchimerism per total 100 000 GEq tested.

²Weeks gestational age (WGA).

³For these subjects, partner or child HLA typing not available to definitively rule out fetal source.

⁴For these subjects, MP HLA typing not available to definitively rule out MP source.

⁵Some subjects had more than one sample tested during the first trimester; these are all listed and delimited by commas.

⁶For subject #14, two pregnancies were followed, and results are listed.
