Can you define what the anion gap is?

Can you define what the anion gap is?

Anion gap: Hi. The most common way to measure anion gap (AG) is to subtract the serum chloride concentration and the serum CO2 concentration from the serum sodium concentration. AG = Na - (Cl + total CO2). The AG is due to unmeasured anions in blood. Depending on lab, normal AG is up to about 12 or 14. In acidotic states such as diabetic ketoacidosis, lactic acidosis, sepsis, etc), AG is increased. ...Read more

Is an anion gap of 14 anything to worry about?

Is an anion gap of 14 anything to worry about?

NotIfYouFeelWell: It's a little high but the usual causes for a delta gap of 1-2 (which is where your number falls) range is usually a lactic acidosis and in some circumstances diabetic acidosis. Do you exercise? Do you drink plenty of water? To really give an accurate interpretation, more information is needed about your medical history, medications you take, and symptoms. ...Read more

What does it mean when your anion gap is high?

What does it mean when your anion gap is high?

Acidosis: It means there is too much acid in your blood at the expense of more negatively charged substances (anions) being consumed (bicarbonate (sodium bicarbonate) (sodium bicarbonate (sodium bicarbonate)) and chloride) than positively charged substances (unmeasured cations h+), which consume the bicarbonate (sodium bicarbonate). ...Read more

My anion gap came back at 5 should I be worrid?

Depends: Interpreting the anion gap really depends on clinical context. An anion gap of 5 could be normal in some people, but could also signify something like low albumin. ...Read more

Should a person worry if anion gap is low at 3.9?

No: This means nothing. Reference ranges are arbitrarily set so that 5% or so of healthy folks fall outside. ...Read more

16+: Each lab has its own range of normals. Ag was a concept designed to help doctors figure out the source of acidosis, just a tool not a measure of how sick you are.. If you are significantly acidotic the ag is useful. If you are not acidotic it is just a number spit out by the lab. A low ag may be seen with multiple myeloma. ...Read more

Hello. I was told I have an anion gap of 18 which is above normal. Is this a big concern?

How do you FEEL?: If you feel okay, I'd ignore it. Reference ranges are set so that a few percent of healthies fall outside on either end, as you have. ...Read more

What does it mean if your anion gap is low and your sodium is normal in the middle of the range? Should i be concerned?

What does it mean if your anion gap is low and your sodium is normal in the middle of the range?  Should i be concerned?

No need for worry: The anion gap is calculated by subtracting serum concentrations of chloride and bicarbonate (sodium bicarbonate) ions from sodium. If it falls below 3 meq/l, it is defined as low. The most common cause is laboratory error. Another less common explanation includes a low serum Albumin concentration. ...Read more

Anion gap 20, glucose101. Not diagnosed with diabetes? Is that what this usually is, could it be something else, and do I need to worry?

High anion gap: A high anion gap (ag) can be caused by: milk-alkali syndrome uremia diabetic ketoacidosis propylene glycol Isoniazid intoxication lactic acidosis ethanol ethylene glycol rhabdomyalysis and Aspirin intoxication. Your glucose of 101 is not elevated. It is always best to speak to the doctor (d) who ordered the glucose and ag to see what they mean in your case. ...Read more
