Just so, what does the anion gap tell you?
Medical Definition of Anion gap. 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.
1
What does a high anion gap indicate?
If your results show a high anion gap, you may have acidosis, which means higher than normal levels of acid in the blood. Acidosis may be a sign of dehydration, diarrhea, or too much exercise. It may also indicate a more serious condition such as kidney disease or diabetes.
2
What is the normal range for anion gap?
The normal value for the serum anion gap is 8-16 mEq/L. However, there are always unmeasurable anions, so an anion gap of less than 11 mEq/L using any of the equations listed in Description is considered normal. For the urine anion gap, the most prominently unmeasured anion is ammonia.
3
What is the most common cause of metabolic acidosis?
Other causes of metabolic acidosis include: Kidney disease (distal renal tubular acidosis and proximal renal tubular acidosis) Poisoning by aspirin, ethylene glycol (found in antifreeze), or methanol. Severe dehydration.

How do you diagnose multiple myeloma?
Blood tests are also used to measure kidney function, calcium levels, and blood cell counts for possible anemia and other low blood counts.
- X-ray.
- Magnetic resonance imaging (MRI).
- Computed tomography (CT or CAT) scan.
- Positron emission tomography (PET) or PET-CT scan.
- Bone marrow aspiration and biopsy.

What does a high bun mean?
A BUN test is done to see how well your kidneys are working. If your kidneys are not able to remove urea from the blood normally, your BUN level rises. Heart failure, dehydration, or a diet high in protein can also make your BUN level higher. Liver disease or damage can lower your BUN level.
6
What is albumin in a blood test?
This test measures the amount of the protein albumin in your blood. Albumin carries substances such as hormones, medicines, and enzymes throughout your body. This test can help diagnose, evaluate, and watch kidney and liver conditions. When your kidneys begin to fail, albumin starts to leak into your urine.
7
What is creatinine in a blood test?
A creatinine blood test measures the level of creatinine in the blood. Creatinine is a waste product that forms when creatine, which is found in your muscle, breaks down. Creatinine levels in the blood can provide your doctor with information about how well your kidneys are working.
8
What is the gap in DKA?
It causes nausea, vomiting, and abdominal pain and can progress to cerebral edema, coma, and death. DKA is diagnosed by detection of hyperketonemia and anion gap metabolic acidosis in the presence of hyperglycemia. Treatment involves volume expansion, insulin replacement, and prevention of hypokalemia.
9
What does a high AST mean?
Inflamed or injured liver cells leak higher than normal amounts of certain chemicals, including liver enzymes, into the bloodstream, which can result in elevated liver enzymes on blood tests. The specific elevated liver enzymes most commonly found are: Alanine transaminase (ALT) Aspartate transaminase (AST)
10
What is ALT in a blood test?
An alanine aminotransferase (ALT) test measures the amount of this enzyme in the blood. Low levels of ALT are normally found in the blood. But when the liver is damaged or diseased, it releases ALT into the bloodstream, which makes ALT levels go up. Most increases in ALT levels are caused by liver damage.
11
What does it mean when your chloride is high?
An increased level of blood chloride (called hyperchloremia) usually indicates dehydration, but can also occur with other problems that cause high blood sodium, such as Cushing syndrome or kidney disease. A decreased level of blood chloride (called hypochloremia) occurs with any disorder that causes low blood sodium.
12
What is acidosis in humans?
Both diarrhea and vomiting can cause this type of acidosis. Lactic acidosis occurs when there's too much lactic acid in your body. Causes can include chronic alcohol use, heart failure, cancer, seizures, liver failure, prolonged lack of oxygen, and low blood sugar.
13
What is a high bun creatinine ratio?
The ratio of BUN to creatinine is usually between 10:1 and 20:1. An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration.
14
What happens when PH of blood decreases?
If unchecked, metabolic acidosis leads to acidemia, i.e., blood pH is low (less than 7.35) due to increased production of hydrogen ions by the body or the inability of the body to form bicarbonate (HCO3−) in the kidney. Its causes are diverse, and its consequences can be serious, including coma and death.
15
What is calcium in blood test?
A blood calcium test is ordered to screen for, diagnose, and monitor a range of conditions relating to the bones, heart, nerves, kidneys, and teeth. The test may also be ordered if a person has symptoms of a parathyroid disorder, malabsorption, or an overactive thyroid.
16
What is globulin in the blood?
Some globulins are produced in the liver, while others are made by the immune system. Globulins, albumins, and fibrinogen are the major blood proteins. The normal concentration of globulins in human blood is about 2.6-4.6 g/dL. The term "globulin" is sometimes used synonymously with "globular protein".
17
Why does multiple myeloma cause low anion gap?
This leads to an increase in unmeasured cations and a low anion gap7, 8). Concomitant severe hypercalcemia and hypoalbuminemia are often contributing factors to a low anion gap in multiple myeloma9). Hypoalbuminemia is probably the commonest cause of a clinically relevant lowered anion gap.
18
What is globulin on a blood test?
Albumin and globulin are two types of protein in your body. The total protein test measures the total amount albumin and globulin in your body. It's used as part of your routine health checkup. It may also be used if you have unexpected weight loss, fatigue, or the symptoms of a kidney or liver disease.
19
What does a high a G ratio mean?
A low A/G ratio may reflect overproduction of globulins, such as seen in multiple myeloma or autoimmune diseases, or underproduction of albumin, such as may occur with cirrhosis, or selective loss of albumin from the circulation, as may occur with kidney disease (nephrotic syndrome).
