Results from this study4

No result from this study comes from a test of the peptide.

Natural levels measured4

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    At delivery, mixed umbilical cord serum thymosin alpha‑1 levels were higher than maternal levels.

    In plain wordsAt birth, the baby's own cord blood thymosin alpha‑1 levels were higher than the mother's levels.

    Summary
    Mixed umbilical cord serum levels (1,466 +/- 940 pg/ml) were higher than maternal levels (P less than or equal to 0.005).

    Summary · context
    To evaluate this further, we obtained maternal venous and newborn mixed cord blood from 90 pregnancies between 20 and 42 weeks of gestation at delivery.

    This result measures the body's own Thymosin alpha-1. Nobody was given the peptide. It is not evidence about taking it.

  2. 02HumanEndogenous levelObservational studyOther

    Maternal thymosin alpha‑1 levels tended to be higher than those of healthy adults; no test result was given.

    In plain wordsMothers' own thymosin alpha‑1 levels tended to be higher than levels in healthy adults.

    Maternal and newborn thymosin alpha‑1 levels were independent of gestational age.

    In plain wordsThe body's own thymosin alpha‑1 levels in mothers and newborns did not depend on gestational age.

    An apparent association (r = 0.51) between maternal and newborn thymosin alpha‑1 levels was inconclusive.
