The lower limit is more affected by increasing coefficient of variation, and its "critical" coefficient of variation of 0.213 corresponds to a ratio of (upper limit)/(lower limit) of 2.43, so as a rule of thumb, if the upper limit is more than 2.4 times the lower limit when estimated by assuming normal distribution, then it should be considered ...

In mathematics, the lower limit topology or right half-open interval topology is a topology defined on ... is a perfectly normal Hausdorff space.
Therefore, the lower limit of the prediction interval is approximately 5 ‒ (2⋅1) = 3, and the upper limit is approximately 5 + (2⋅1) = 7, thus giving a prediction interval of approximately 3 to 7. Diagram showing the cumulative distribution function for the normal distribution with mean (μ) 0 and variance (σ 2) 1.
[3] [2] Although 70 mg/dL (3.9 mmol/L) is the lower limit of normal glucose, symptoms of hypoglycemia usually do not occur until blood sugar has fallen to 55 mg/dL (3.0 mmol/L) or lower. [3] [2] The blood-glucose level at which symptoms of hypoglycemia develop in someone with several prior episodes of hypoglycemia may be even lower. [2]
In analytical chemistry, the detection limit, lower limit of detection, also termed LOD for limit of detection or analytical sensitivity (not to be confused with statistical sensitivity), is the lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) with a stated confidence level (generally 99%).

Resting heart rates of less than 50 BPM are often normal during sleep in young and healthy adults and athletes. [2] In large population studies of adults without underlying heart disease, resting heart rates of 45–50 BPM appear to be the lower limits of normal, dependent on age and sex.
