Afterward, the site may be slightly sore. An anion gap is calculated by using the results of an electrolyte blood test. 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. Acidosis may indicate that you are dehydrated, having diarrhea, or you are doing too much exercise. An electrolyte blood test is used to calculate an anion gap. In this article, we will tackle the meaning behind the anion gaps as well as its causes. This article may be too technical for most readers to understand.

Please to , without removing the technical details. Chloride is the most abundant anion in the fluid surrounding the cells. Acidosis in particular can be life-threatening, so it's important to find the cause and treat it as soon as possible. Electrolytes have an electrical charge — some are positive and others are negative. When metabolic acidosis occurs, the hydrogen ions cations reacts with bicarbonate anions, resulting in decreased concentration of the measured anion and increased concentration in the unmeasured anions, leading to a gap.

A large increase in other positively charged ions, such as calcium and magnesium, can also lower the anion gap. Being dehydrated or retaining water in your body can affect your results. Because the anion gap is calculated from the results of the electrolyte panel, accurate measurement of the individual electrolytes is necessary. Any disease or condition that affects the amount of fluid in the body, such as dehydration, or affects the lungs, kidneys, , or breathing has the potential to cause a fluid, electrolyte, or pH imbalance acidosis or alkalosis. In this condition the kidneys do not take in enough bicarbonate and it is lost in urine. Other factors There are a few more rare causes of low anion gap.
