Stewart Physicochemical Analysis of Acid-Base:
Advanced physicochemical mapping utilizing strong water dissociation chemistry parameters.
Measures sodium-chloride differential loops. Reference normal baseline constraint is set to 38 mEq/L.
Represents the actual charge gap that must balance out plasma electrical neutrality. Accounts for measured Bicarbonate plus the dynamic negative charge contributed by Albumin weak acids.
Unmasks hidden organic tissue acid metrics when values climb greater than 0.
SIG Etiology Differential Matrix:
- K Ketones (Diabetic, Starvation, Alcoholic Ketoacidosis States)
- U Uremia (Advanced Renal Failure Retention Accumulations)
- L Lactate (Type A Hypoperfusion / Type B Metabolic Inefficiencies)
- T Toxins (Toxic Alcohol Ingestions: Methanol, Ethylene Glycol, Salicylates)
