STAR LABA shared sample does not guarantee a shared result.
The evidence
NIST’s CannaQAP Exercise 3 examined moisture measurements in one supplied hemp material. Its report, published 28 April 2025, describes a wide spread of results from participating laboratories using different drying methods. The authors identify a need for consistent methods to improve measurement accuracy and precision. [1]
Why a reader should care
Our editorial interpretation: a moisture number is incomplete without its measurement context. Before comparing reports, record the material, method and reporting basis. Two percentages with identical units may still describe results obtained under different analytical definitions.
Limits of the finding
This exercise concerns one hemp material and laboratory comparability. It is not a validation of every concentrate matrix, a product safety verdict or evidence for a particular POSH STAR batch. The report is an established 2025 publication, not a newly announced discovery. [1]
A useful documentation habit
Retain the original report alongside any summary. If two values disagree, describe that discrepancy and ask what each method measures before assuming one material changed. This is a reading practice, not drying or processing guidance.
