Serum Osmolality

Calculate serum osmolality using the sample's sodium, blood urea nitrogen (BUN), glucose and ethanol levels. Formula: Serum osmolality = 2*Na + BUN/2.8 + glucose/18 + alcohol/3.7 Normal range = 275 to 295 mOsm/kg Principle: Osmolality is a special variation of molality, and is a measure of the number of dissolved, osmotically active, particles in a fluid, and is… Continue reading Serum Osmolality

Standard Deviation (SD) Calculator from Reference Range

Determine the Standard Deviation and Mean from the low and high limits of the acceptable or reference ranges. Please click here if you would like to calculate the standard deviation using a given set of data points. Formula: Mean = (Low Limit + High Limit) /2Standard Deviation = (Mean - Low Limit) / 2**For example,… Continue reading Standard Deviation (SD) Calculator from Reference Range
