Osmolar Gap Solution

STEP 0: Pre-Calculation Summary

Formula Used

Osmolar Gap = Measured Osmolality-Calculated Serum Osmolality
OG = MO-O_serum
This formula uses 3 Variables

Variables Used

Osmolar Gap - (Measured in Mole per Cubic Meter) - Osmolar Gap is an indication of unmeasured solute in the blood.
Measured Osmolality - (Measured in Mole per Cubic Meter) - Measured Osmolality refers to the measured concentration of dissolved particles of chemicals and minerals such as sodium and other electrolytes in given serum.
Calculated Serum Osmolality - (Measured in Mole per Kilogram) - Calculated Serum Osmolality refers to the calculated concentration of dissolved particles of chemicals and minerals such as sodium and other electrolytes in given serum.

STEP 1: Convert Input(s) to Base Unit

Measured Osmolality: 3 Millimole per Liter --> 3 Mole per Cubic Meter (Check conversion here)
Calculated Serum Osmolality: 5 Millimole per Kilogram --> 0.005 Mole per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

OG = MO-O_serum --> 3-0.005

Evaluating ... ...

OG = 2.995

STEP 3: Convert Result to Output's Unit

2.995 Mole per Cubic Meter -->2.995 Millimole per Liter (Check conversion here)

FINAL ANSWER

2.995 Millimole per Liter <-- Osmolar Gap

Peak Resolution in Chromatography

Go Peak Resolution = (Retention Volume of Molecule 2-Retention Volume of Molecule 1)/((Width of Chromatographic Peak of Molecule 1+Widths of Chromatographic Peak of Molecule 2)/2)

Blood Urea Nitrogen using Calculated Serum Osmolality

Go Blood Urea Nitrogen = 2.8*((Calculated Serum Osmolality)-(2*Serum Sodium)-(Serum Glucose/18))

Serum Glucose using Calculated Serum Osmolality

Go Serum Glucose = 18*((Calculated Serum Osmolality)-(2*Serum Sodium)-(Blood Urea Nitrogen/2.8))

Serum Sodium using Calculated Serum Osmolality

Go Serum Sodium = ((Calculated Serum Osmolality)-(Serum Glucose/18)-(Blood Urea Nitrogen/2.8))/2

Calculated Serum Osmolality

Go Calculated Serum Osmolality = (2*Serum Sodium)+(Serum Glucose/18)+(Blood Urea Nitrogen/2.8)

Width of Chromatographic Peak using Column Efficiency

Go Width of Chromatographic Peak = Retention Volume/(sqrt(Column Efficiency/16))

Retention Volume using Column Efficiency

Go Retention Volume = Width of Chromatographic Peak*(sqrt(Column Efficiency/16))

Increase of Splicing Potential by Wild-type Sequence

Go Splicing Potential = log10(Weight Factor for Increase of Splicing Potential)

Column Efficiency in Chromatography

Go Column Efficiency = 16*((Retention Volume/Width of Chromatographic Peak)^2)

Calculated Serum Osmolality using Osmolar Gap

Go Calculated Serum Osmolality = Measured Osmolality-Osmolar Gap

Measured Osmolality using Osmolar Gap

Go Measured Osmolality = Osmolar Gap+Calculated Serum Osmolality

Osmolar Gap

Go Osmolar Gap = Measured Osmolality-Calculated Serum Osmolality

Total Volume of Mobile Phase within Column given Retention Factor

Go Void Volume = Retention Volume/(Retention Factor+1)

Retention Volume using Retention Factor

Go Retention Volume = Void Volume*(Retention Factor+1)

Decrease of Splicing Potential by Mutant Sequence

Go Splicing Potential = -log10(Weight Factor)

Plasma Osmolality

Go Plasma Osmolality = (2*Sodium Concentration in Plasma)

Plasma Concentration using Plasma Osmolality

Go Sodium Concentration in Plasma = Plasma Osmolality/2

Osmolar Gap Formula

Osmolar Gap = Measured Osmolality-Calculated Serum Osmolality
OG = MO-O_serum

What is Osmoregulation?

Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis.

How to Calculate Osmolar Gap?

Osmolar Gap calculator uses Osmolar Gap = Measured Osmolality-Calculated Serum Osmolality to calculate the Osmolar Gap, The Osmolar Gap formula is defined as an indication of unmeasured solute in the blood. It is determined by the measured osmolality (MO) minus the calculated osmolality (CO). Osmolar Gap is denoted by OG symbol.

How to calculate Osmolar Gap using this online calculator? To use this online calculator for Osmolar Gap, enter Measured Osmolality (MO) & Calculated Serum Osmolality (O_serum) and hit the calculate button. Here is how the Osmolar Gap calculation can be explained with given input values -> 2.995 = 3-0.005.
