Learn more about laboratory tests reference ranges and understanding results.

. Having low levels of albumin a negatively charged protein can cause a decreased anion gap. The serum anion difference should be between three and ten mEqL with an average of six mEqL. Normal results generally fall between 3 and 10 mEqLHowever normal ranges may vary by lab. A retrospective study of 6868 sets of serum electrolytes among hospitalized patients 3 for example revealed incidences of increased and reduced anion gap to be 376 and 29 respectively.

If the value of anion gap is too high or too low it indicates something wrong in your body. The anion gap value is. These authors found that relationship between anion gap and albumin varied depending on the bicarbonate level. Treatment for an abnormal anion gap will focus on the underlying cause.

A high anion gap itself does not produce symptoms but it may indicate an imbalance in blood acid levels such as metabolic acidosis. A patient with a markedly negative AG is presented and a. Anion gap is calculated as value of sodiumpotassium-chloridebicarbonate. The commonest cause is lab error particularly in the measurement of the serum sodium.

On the other hand if a subject has hypoalbuminemia it also leads to low anion. Is most often due to increased serum lactate or acetoacetate. This helps your healthcare provider diagnose acid-base problems. Hypoalbuminemia is the most common cause of a low anion gap.

Since low anion gap results are uncommon retesting is often done to ensure the results are accurate. Increase in the AG i. When these disorders develop AG is typically elevated or within the normal range. Is there anything else I need to know about an anion gap blood test.

Anion Gap Blood Does this test have other names. Non random analytical errors increased Na increased viscosity iodide ingestion increased lipids Decrease in unmeasured anions albumin dilution Increase in unmeasured cations multimyeloma cationic IgG paraprotein hypercalcaemia hypermagnesaemia lithium OD polymixin B. The balance of positively and negatively charged ions dictates how acidic or alkaline the blood is. Other causes of metabolic acidosis eg renal tubular acidosis may have a normal anion gap.

Classically we are taught to look out for an elevated anion gap in patients with a metabolic acidosis. The anion gap AG is usually a clue to a variety of metabolic acidoses and the presence of mixed acid-base disorders. Also it may be a handy clinical clue for the diagnosis of life-threatening intoxications or occult neoplasms such as multiple myeloma. Low anion gap.

High and low anion gaps are symptoms of blood pH problems. Although much less common a low anion gap can also be a useful sign and there are a variety of causes. High concentrations of positively charged proteins can also cause this change. The anion gap is really not a gap at all it just represents the anions we dont usually measure.

This test looks at electrically charged particles in your blood. Carvounis 2000 related anion gap to albumin among 432 patients admitted to a medical intensive care unit. Other causes include hypernatremia certain gammopathies myeloma and severe hypercalcemia. The anion gap can be normal high and low.

Abnormal anion gap is a relatively common occurrence among hospitalized patients with increased anion gap being far more common than reduced anion gap. Rapid and shallow breathing. LOW ANION GAP. As previously discussed high serum.

A low anion gap is a useful diagnostic tool but its clinical significance is often unrecognized. Physically a low anion gap is a smaller-than-normal difference between positively and negatively charged ions in bodily fluids says Lab Tests Online. The ratio of the change in anion gap to the change in albumin was 145 mM per mgdL for patients with a normal to high bicarbonate and 189 mM. From the retrospective study on the 6868 sets of serum electrolyte among hospitalized patients we found the incidences of normal increased and decreased anion gaps were 595 376.

What is this test. Some symptoms of metabolic acidosis include 9. A low anion gap occurs rarely and causes alkalosis. The anion gap value is reported in units of milliequivalents per liter mEqL.

The reference range of anion gap obtained from 124 healthy volunteers was 5-12 mmoll which was low and confirmed the reports from other studies 3-11 mmoll using ion-selective electrode. Talk to your health care provider to learn what your results mean. Lab error lithium intoxication and bromide ingestion can all also cause a low anion gap. Whereas the presence for a high anion gap educes the consideration of a differential diagnosis by reflex in daily clinical practice a low anion gap often does not elicit the same warning to clinicians and hence often remains either undiscovered or neglected.

Low Anion Gap. The total CO2 content contains serum bicarbonate as well as other sources of carbon dioxide with serum HCO3- accounting for approximately 95 of the total CO2 content. Although there are several possibilities for low anion gap levels some of the possibilities include something as simple as having diarrhea or exercising too much. A high anion gap suggests metabolic acidosis ketoacidosis lactic acidosis.

Also having kidney issues can cause low anion gap levels because there is too much acid in the urine. A low or high anion gap alone cannot diagnose a medical condition so a doctor will perform a variety of other tests before. An anion gap test checks the levels of acid in your blood. The AG represents anions such as proteins phosphates sulfates and organic anions.

Less often the AG is reduced into the low range or even becomes negative. AG Na - Cl- HCO 3 typically about 10 to 12 mmol b.
