Digoxin-Like Substance in Amniotic Fluid – Fact or Artifact?
Bibliographic record
Abstract
A digoxin-like immunoreactive substance (DLIS) has been reported in the amniotic fluid. Since radioimmunoassay kits are standardized using serum-based standards, we hypothesized that measurement of DLIS may be an artifact related to the low protein content of amniotic fluid. We analyzed 12 amniotic fluid samples before and after supplementation with lyophilized human serum. The means +/- SDs for DLIS (nmol/l) at protein concentrations of 0, 32 and 63 g/l were 1.4 +/- 0.16, 0.6 +/- 0.09, and 0.4 +/- 0.09 nmol/l, respectively. We, therefore, hypothesize that DLIS in amniotic fluid may in part be explained by a technical artifact.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
