Higher serum sodium levels, even within the normal range, are linked to increased risk of developing hypertension and heart failure. People with sodium levels of 140 mmol/L or higher had up to a ...

These findings imply that the change in reference range led more clinicians to consider either that patients had developed biochemical subclinical hypothyroidism (raised TSH with normal range free ...

Reference ranges are provided by the laboratory and do not vary based on individual dogs. For example, the normal reference ...

Harmonized Reference Ranges for Circulating Testosterone Levels in Men of Four Cohort Studies in the USA and Europe. Journal of Clinical Endocrinology & Metabolism , 2017 DOI: 10.1210/jc.2016-2935 ...

All too often we think that any lab value that is outside the lab's stated reference interval represents a disease process and needs further evaluation. That brings to mind two problems. Normal ...

The typical range of reference for TSH levels is anywhere between 0.45 and 4.5 milliunits per liter (mU/L). A recent study suggests that the normal range should be more like 0.45 to 4.12 mU/L.

The other class of assay reports higher detection limits (>10kIU/L) and cites a TgAb "normal reference range". These detectable "normal range" values are likely to represent non-specific assay ...

And basically, really, reference ranges are ranges that we establish by looking at normal patients and we establish the reference range by looking at 95% of the normal population or having that as our ...

In the data from China, 73.5% of adults with subclinical hypothyroidism and 60% with overt hypothyroidism using current reference ranges were reclassified as having normal thyroid function when ...
