High anion gap metabolic acidosis
Dec 05, · High Anion Gap. If your anion gap blood test got an elevated result, it could mean that your blood is too acidic. Acidosis could be the other reason for the same result. Acidosis may indicate that you are dehydrated, having diarrhea, or you are doing too much exercise. Getting a high anion gap result, or having acidosis, is associated with conditions such as. Jan 22, · What Your Results Mean If your doctor says you have a high anion gap, you may have a higher than normal amount of acid in your blood. The .

A blood test called a serum anion gap test is used by healthcare providers to diagnose conditions caused by an imbalance between the acids and bases in the blood.
The results are reported as part of a comprehensive metabolic panel. The anion gap test, along with a physical exam, a focused history from the patient, and additional tests, helps healthcare professionals provide specific treatments, especially when patients present with a sudden illness such as altered mental status or acute renal failure.
An anion gap test can help diagnose metabolic acidosis, a life-threatening condition that occurs when your blood becomes too acidic. It can also detect an alkalosis, when your blood is not acidic enough. It is important to find the cause and treat it as soon as possible.
Metabolic acidosis may occur due to:. Lactic acid builds up following vigorous exercise lactic acidosisbut this is not typically enough to cause changes in the body's pH. You might need this test if you experience symptoms of an electrolyte imbalance—such as fatigue, shortness of breath, nausea and vomiting, rapid heart rate, or low blood pressure. The anion gap is not ordered as a separate test.
This value is derived from the measurements of blood electrolytes. The test you will see ordered would be an electrolyte panel, basic what is nutella snack and drink panel BMPor comprehensive metabolic panel CMP. No specific preparation is needed before the test. If you are having this done as an outpatient, you may be sent to the lab for a blood draw.
A healthcare professional uses a needle to puncture your skin, access the vein, and draw a small sample of blood into a tube. The entire blood drawing process is usually less than five minutes long. The test is relatively safe. You may have slight pain or bruising at the injection site. The tube of blood is then sent to the laboratory for analysis. The anion gap is calculated from the values obtained for the electrolytes. The most common method of evaluation of metabolic acidosis involves the Henderson-Hasselbalch equation and the Lewis model interpretation of biological acidosis, which evaluates the plasma concentration of hydrogen ions.
A high anion gap means you have more acid in your blood than normal. A low anion gap means you have a lower amount of acid in your blood than normal, but this result is uncommon and usually due to a what volt battery is in a motorcycle error.
A low or high anion gap does not necessarily mean that you have a serious health problem. The normal range varies from person to person, so make sure you ask your doctor to interpret the results of the test for you.
Correcting the underlying cause of the high anion gap metabolic acidosis is the primary way to mitigate potential serious health consequences. In mild to moderate acidosis, treatment could be limited to supportive measures, such as intravenous IV fluids and respiratory support.
Alkalization therapy is reserved for individuals with severe acidosis pH less than 7. Sign up for our Health Tip of the Day newsletter, and receive daily tips that will help you live your healthiest life. American Association of Clinical Chemistry.

Nov 22, · A high anion gap may indicate metabolic acidosis, which requires medical management. The treatment of metabolic acidosis typically requires addressing the underlying cause. Some possible treatments for metabolic acidosis include detoxification if caused by drugs or toxins and insulin if the condition is caused by diabetes [ 9 ]. A high anion gap means you have more acid in your blood than normal. A low anion gap means you have a lower amount of acid in your blood than normal, but .

Note that each number in parentheses [1, 2, 3, etc. The anion gap is a value calculated from the results of an electrolyte blood test which informs clinicians about the balance of positively and negatively charged particles in the blood.
The anion gap is a value that represents the difference between positively charged ions cations and negatively charged ions anions in the blood. The anion gap cannot be directly measured, instead, it is calculated from the results of an electrolyte panel, another type of blood test.
The anion gap is calculated using the concentrations of the major anions in the blood, chloride and bicarbonate , and the major cations, sodium and potassium. However, the concentration of potassium in the blood is usually much lower compared to sodium, chloride, and bicarbonate. Therefore, it is common practice to not use potassium when calculating the anion gap, as it usually has little effect [ 1 ]. In the body, the total positive charge from cations should equal the total negative charge from anions in the blood to maintain overall neutrality.
However, blood tests usually do not measure all types of ions. This means the anion gap gives us a picture of the unmeasured anions and cations in the blood. There are normally more unmeasured anions than cations, hence there is usually an anion gap [ 2 ]. Clinically, the anion gap value is primarily used to help evaluate acid-base disorders , which occur when the concentration of acids and bases in the blood becomes unbalanced [ 2 ]. Although the term anion gap usually refers to the concentrations of cations and anions in the blood, it can also refer to their concentrations in the urine, which is also clinically useful [ 3 ].
Normal ranges can vary between laboratories due to differences in equipment, techniques, and chemicals used. If your results are outside of the normal range, it may not necessarily mean there is something wrong. Always talk with your doctor to learn more about your test results.
Some older types of tests used different techniques to measure electrolytes, which give different results. Test results should be interpreted by a doctor who can take into account your medical history and other test results. The anion gap is primarily used to determine the cause of metabolic acidosis , a condition where the body is producing too much acid or not enough acid is being removed from the body. The list below details some potential causes of metabolic acidosis that is associated with a high anion gap.
A normal anion gap during metabolic acidosis may indicate a different set of causes [ 8 ]. A high anion gap itself does not produce symptoms, but it may indicate an imbalance in blood acid levels, such as metabolic acidosis. Some symptoms of metabolic acidosis include [ 9 ]:.
Talk with your doctor if your anion gap test results are high. A high anion gap may indicate metabolic acidosis, which requires medical management. The treatment of metabolic acidosis typically requires addressing the underlying cause. Some possible treatments for metabolic acidosis include detoxification if caused by drugs or toxins and insulin if the condition is caused by diabetes [ 9 ].
Test results should always be interpreted by a doctor who can take into account your medical history and other test results. The occurrence of a low anion gap value is very rare.
When it is reported, the most common cause is a laboratory error. In a study of over 67, calculations of the anion gap, the prevalence of a low anion gap value was found in only 0.
Some other potential causes of a low anion gap are as follows [ 2 , 38 , 39 ]:. A low anion gap may be caused by a number of different conditions. Symptoms will depend on the underlying cause. Treatment will depend on the underlying cause as well.
It is worthwhile to repeat the electrolyte blood test and recalculate the anion gap value to ensure that the low anion gap value is not an outcome of a laboratory error in measurement.
