What does gap mean in lab results?

What does gap mean in lab results?

What is an anion gap blood test? An anion gap blood test is a way to check the levels of acid in your blood. The test is based on the results of another blood test called an electrolyte panel. Electrolytes are electrically charged minerals that help control the balance of chemicals in your body called acids and bases.

What causes a high anion gap?

High anion gap acidoses are most often due to ketoacidosis, lactic acidosis, chronic kidney disease, or certain toxic ingestions. Normal anion gap acidoses are most often due to gastrointestinal or renal HCO 3 − loss.

What are symptoms of high anion gap?

A high anion gap itself does not produce symptoms, but it may indicate an imbalance in blood acid levels, such as metabolic acidosis….Symptoms

  • Nausea.
  • Vomiting.
  • Rapid and shallow breathing.
  • Fatigue.
  • Rapid/abnormal heartbeat.
  • Low blood pressure.
  • Confusion.
  • Headaches.

How high is too high for anion gap?

An elevated anion gap (greater than 12 mEq/L; “mud pilers,” which is an acronym for the main causes of elevated anion gap) may indicate: Methanol. Uremia. Diabetic ketoacidosis.

How is high anion gap treated?

The most common alkalizing agent is sodium bicarbonate, but sodium and potassium citrate are alternative options. In the event of severe, recalcitrant acidosis, it may be appropriate to treat empirically with alcohol dehydrogenase inhibitors (fomepizole or ethanol) and prepare the patient for emergent hemodialysis.

How can I lower my anion gap?

How do you lower anion gap?

Theoretically, increase in serum concentration of the cations potassium, calcium or magnesium decreases the anion gap.

How do you treat high anion gap?

How do I lower my anion gap?

How do you fix acidosis?

Acidosis treatment might include:

  1. oral or intravenous sodium bicarbonate to raise blood pH.
  2. medications to dilate your airways.
  3. continuous positive airway pressure (CPAP) device to facilitate breathing.
  4. sodium citrate to treat kidney failure.
  5. insulin and intravenous fluids to treat ketoacidosis.

Is anion gap of 18 high?

and a normal anion gap is approximately 10—16 mEq/L. An anion gap of 17 or higher represents an increased anion gap, and an anion gap of 9 or lower represents a decreased anion gap.

What does a high anion gap mean on a blood test?

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.

What causes low anion gap in blood?

Acidosis can also be brought on by too much exercise. If your doctor says you have a low anion gap, you might have a lower than normal amount of acid in your blood. This result isn’t common, and sometimes it’s due to a lab error. Your doctor may ask the lab to do the test again to double-check the numbers.

Should I talk to my doctor about my anion gap results?

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.

What is the anion gap in electrolytes?

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. This is a useful measure to diagnose diseases and disorders associated with an acid/base imbalance in the body. What Is the Anion Gap?
