Modern analyzers use ion-selective electrodes which give a normal anion gap as <11 mEq/L. Therefore, according to the new classification system, a high anion gap is anything above 11 mEq/L. A normal anion gap is often defined as being within the prediction interval of 3–11 mEq/L, [8] with an average estimated at 6 mEq/L. [9]
In nephrotic syndrome, protein loss can be as great as 3.5 grams over 24 hours, much of which is albumin, itself leading to hypoalbuminemia. [3] In children, nephrotic syndrome is commonly a primary disease process that is largely idiopathic , although more genetic causes are being identified with the cost and accessibility of whole exome ...
Urine NH 4 + is difficult to measure directly, but its excretion is usually accompanied by the anion chloride. A negative urine anion gap can be used as evidence of increased NH 4 + excretion. In a metabolic acidosis without a serum anion gap: A positive urine anion gap suggests a low urinary NH 4 + (e.g. renal tubular acidosis).
Albumin/creatinine ratio — used to diagnose microalbuminuria [15] Urine osmolality — measure of the solute concentration of urine [16] Urine specific gravity ― another measure of urine concentration [16] Urine electrolyte levels — measurement of electrolytes such as sodium and potassium in urine [17]
Result 1: if there is a normal anion gap acidosis, the (AG – 12) part of the equation will be close to zero, the delta ratio will be close to zero and there is no mixed acid–base disorder. Your calculations can stop here. A normal anion gap acidosis (NAGMA) has more to do with a change in [Cl −] or [HCO − 3] concentrations.
This is termed the albumin/creatinine ratio (ACR) [10] and microalbuminuria is defined as ACR ≥3.5 mg/mmol (female) or ≥2.5 mg/mmol (male), [11] or with both substances measured by mass, as an ACR between 30 and 300 μg albumin/mg creatinine. [12] For the diagnosis of microalbuminuria, care must be taken when collecting sample for the urine ...

A basic metabolic panel (BMP) is a blood test consisting of a set of seven or eight biochemical tests and is one of the most common lab tests ordered by health care providers.
