Frozen or fresh? new study tests vitamin d lab accuracy
NCT ID NCT07565064
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether storing blood samples (frozen or at different temperatures) changes the accuracy of a vitamin D test called the ALPCO 25(OH) Vitamin D CLIA Kit. Researchers will compare results from fresh blood with those from stored samples in 80 healthy adults. The goal is to see if labs can use stored samples without affecting test reliability.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could confirm that the ALPCO vitamin D test kit works reliably on both fresh and stored blood samples, making lab testing more flexible.
- What could go wrong
- This is a small, early-stage lab study, not a treatment trial. It only tests measurement stability, not health outcomes, so results may not affect patient care directly.
