Blood analysis of the anion gap : Information About Test

What is the blood analysis of the anion gap?

Blood analysis of the anion gap: Information About Test -The blood analysis of the anionic gap is a way to measure the levels of acidity in the blood. The test is based on the results of another blood test called an ionogram. Electrolytes are electrically charged minerals that help control the balance of chemicals called acids and bases in the body. Some of these minerals have a positive electric charge. Others have a negative electrical charge. The anion gap measures the difference (gap) between electrolytes with a negative and positive charge. A very high or low anion gap could be a sign of a problem in the lungs, kidneys, or other body system or device.

Other names: anion gap, anionic imbalance, anion gap, anion gap

For what do you use it?

Blood analysis of the anionic gap is used to determine if there is an electrolyte imbalance (electrolyte imbalance) or too high or too low acidity in the blood. Very high acidity is known as acidosis. The too low acidity is known as alkalosis.

Why do I need a blood test of the anion gap?

Your doctor or health professional may have requested a blood test of the anion gap if you show signs of imbalance in blood acid levels, for example:

• Shortness of breath
• Vomiting
• Abnormal heartbeat
• Confusion

What happens during a blood test of the anion gap?

The anion gap is obtained from the results of the blood electrolyte analysis (ionogram). A health professional uses a small needle to take a blood sample from a vein in an arm. After inserting the needle, remove a small amount of blood and place it in a test tube. You may feel mild discomfort when the needle is inserted or removed. This process usually takes less than five minutes.

Will I have to do something to prepare for the test?

The blood analysis of the anion gap does not require any special preparation. If your doctor has ordered other tests with your blood sample, you may be instructed not to eat or drink anything for several hours before the test. Your doctor or health professional will tell you if you should follow any special instructions.

Does this test have any risk?

The risks of this blood test are minimal. You may feel mild pain or a bruise where the needle is inserted, but most symptoms disappear quickly.

What do the results mean?

If your results show a high anion gap, you may have acidosis, that is, higher than normal levels of acidity in the blood. Acidosis may be a sign of dehydration, diarrhea or too much exercise. It could also indicate a more serious problem such as kidney disease or diabetes.

If your results indicate a low anion gap, you may have a low level of albumin, a protein in the blood. This could indicate kidney problems, heart disease or certain types of cancer. Since the results of a low anion gap are rare, the test is usually repeated to confirm them. Ask your doctor or health professional what your results mean.

Is there anything else I need to know about the blood test of the anion gap?

The blood analysis of the anionic gap can give important information about the acid-base balance in your blood. However, because the range of normal results is broad, your doctor or health professional may recommend additional tests to make the diagnosis.
