A low anion gap is relatively rare but may occur from the presence of abnormal positively charged proteins, as in multiple myeloma.
The Anion Gap is an approximate measurement of ions, that is molecules with a charge, either negative or positive. Sodium and potassium are positively charged and therefore called cations; this is why they are often represented as Na+ and K+ respectively. These two are the main cations measured in the blood.  My other question is on multiple myelona (cancer of the white blood/plasma cells) which i read also can cause a low test result of anion gap .. if i had something like that developing after 13 years of CFIDS.. What further is confusing about this is I have very low D3 and in my research on anion gap I saw that D3 deficiency affects anion gap the other way to my results and would make my anion gap result higher (not lower) than it would be without a D3 deficiency.. If anion-gap metabolic acidosis is identified, the AG may be used to help monitor the effectiveness of treatment and the underlying condition. Specifically, the anion gap evaluates the difference between measured and unmeasured electrical particles (ions or electrolytes) in the fluid portion of the blood. 1. Anion gap (AG or AGAP) is a value calculated using the results of an electrolyte panel. It is used to help distinguish between anion-gap and non-anion-gap metabolic acidosis. My blood biochem. test results from last week have come back showing my anion gap result is abnormal and two numbers below the normal range. On researching this I've found out low anion gap is uncommon. What further is confusing about this is I have very low D3 and in my research on anion gap I saw that D3 deficiency affects anion gap the other way to my results and would make my anion gap result higher (not lower) than it would be without a D3 deficiency.. Anions are electrons that have a negative charge. They differ from cations which have a positive charge. In medical terms, the anion gap is the difference between the amount of anions and cations in a person's blood. The anion gap may be high, normal or low. This difference may be caused by diabetes or by a condition known as acidosis. An anion gap test is also conducted as a routine after a condition has been diagnosed in order to monitor the progress of the treatment or the progression of the condition if it is untreated. There are many conditions that may warrant an anion gap blood test. Anion gap: A measurement of the interval between the sum of routinely measured cations minus the sum of the routinely measured anions in the blood. The anion gap = (Na+ + K+) - (Cl- + HCO3-) where Na-is sodium, K+ is potassium, Cl-is chloride, and HCO3- is bicarbonate. The anion gap can be normal, high, or low. A high anion gap indicated metabolic acidosis, the increased acidity of the blood due to metabolic processes. A low anion gap is relatively rare but may occur from the presence of abnormal positively charged proteins, as in multiple myeloma The anion gap is the difference in the measured cations (positively charged ions) and the measured anions (negatively charged ions) in serum, plasma, or urine.  The test measures the anion gap, which essentially is the difference between the level of negatively charged ions, or anions, and the level of positively charged ions, or cations, that are in the blood. When interpreting the anion gap test results, other test results are considered as well, like an arterial blood gas test. In addition, a full blood count, including chloride and glucose, usually is performed. Answers. Best Answer: An anion gap is the sum of routinely measured cations minus the routinely measured anions in blood. It is measured because it is often the first laboratory sign of an acid-base disorder. The normal range is 5 - 16 mmol/L.  The Anion gap is the difference in the cations and anions in the body. Cations are positively-charged ions while anions are negatively-charged ions. A low anion gap is usually caused by hypoalbuminemia, a decrease in albumin in the blood. Albumin is an anion which when decreased, it allows other anions such as bicarbonate and chloride to be retained.
