Metabolic test low carbon dioxide plasma or serum??


Laulau

Recommended Posts

Anyone know what a low co2 level would mean? Saw my 2 year old metabolic test results and the carbon dioxide plasma or serum was at 18.7? All else looked normal. Thank you!

This link has some information.  Why was it tested?  It isn’t a routine test.

Carbon dioxide in blood

It was part of a metabolic screening to check for things like anemia. The rest of the results came out in a normal range just don’t understand what and why for this specific result “carbon dioxide plasma or serum”. Thanks!

As a follow-up the dr said if she was crying/upset during the blood draw, that would account for it…which she definitely  was!!!

I’m glad it had an easy explanation!  That makes sense, crying,breathing hard, breathing out more CO2, leading to a lower level.

Laulau et Al,

Let me first say RMJ has given you a good resource.

RMJ thanks for that link.....I have quoted that site myself and it is helpful.

I hope it was just a temporary drop in their CO2 levels......but I would be afraid it might be of a more chronic nature....

As far as I understand it......unless if the C02 levels come back low again then there is not much to worry about....

I had a false positive once for Hepatitis due to a recent sickness but later found out it was a false alarm....

So I feel your concern......but as I understand it....

If you or your child continues do have consistently low CO2 levels then it could be from a chronic metabolic issue or an underlying cause triggering low CO2 levels etc.

A quick way to test this is (If their is a chronic condition) underlying the low CO2 test is to do a pH test on her urine....

pH test's strips are commonly available at most Pharmacies and would put your mind at ease.....that there is not a chronic issue at play here.

This article by the Kidney Coach website explains it well.....because if the CO2 levels are chronically low due to a metabolic disorder it will (As far as I understand it) will show up in your/their Urine pH......due to being low in either (Calcium, Potassium or Magnesium)  IE an electrolyte imbalance in the blood etc...

https://www.kidneycoach.com/causes-of-kidney-disease/magnesium-citrate-its-use-in-renal-disease/

Magnesium Citrate is the easiest way to restore the "Metabolic Homeostasis" if indeed that is the case....

The article will explain in  more detail why this is so....

a short quote from Acid Base balance or "Homeostasis' part of the article so you won't have to read it all to till you get a chance....

"Buffering Systems- exist in many tissues and work to regulate pH values minute to minute. Most critical of these are the blood-based buffering systems, which rely on carbon dioxide and water and alkaline minerals such as calcium, potassium, and magnesium, to maintain blood pH. When the blood is too acidic, alkaline minerals (eg. calcium, potassium, and magnesium) are leached from the bones, and magnesium is released from the muscles to offset the acidity in the blood."

And in short why if your body gets low in Magnesium you could have low C02 levels.....

But no worries the pH test of their/your urine will quickly tell you if their is an underlying metabolic cause? or at least  if their is a cause for more concern or if it only related to the excited condition of drawing the blood etc.

I hope this is helpful but it is  not medical advice.

Posterboy,

Thanks for this information…. It does look like on the metabolic screening her calcium and potassium where in the normal range so sounds like to your point things are in line

      Regarding the discrimination you asked about, it is a lot more easy now to discriminate when you're supposed to answer whether or not you have celiac disease on job applications, and from what I've seen, MANY companies now include this question on their applications:

      People with coeliac disease have an altered gut biome compared with those who do not, which may be associated with gut inflammation. Although the gut biome recovers on a gluten-free diet, there are still significant differences at 2 years. In a mouse model of coeliac disease, supplementation with the soluble dietary fibre, inulin, increased the number of beneficial microbes and reduced gut inflammation. Inulin is used by some plants as carbohydrate store, it is a complex polymer of fructose in the same way that starch is a complex polymer of glucose. Inulin cannot be digested by humans but serves as food source for some gut bacteria. Inulin is present in many vegetables but the richest sources are (g/100g): chicory root 41.6 Jerusalem artichoke 18.0 dandelion greens 13.5 garlic 12.5 leeks 6.5 onions 4.3 The Scientist: Fiber-Metabolizing Bacteria Could Boost Gut Health in Celiac Disease

      Hi Ginger38 Well done you for pushing through the pain barrier of eating gluten, when you know each mouthful is making you poorly.  I went through the same thing not long ago, my biopsy was for dermatitis herpetiformis. Result positive, so 95% certain I have gut coeliacs too. But my bloods were negative, so very pleased I went for the gluten challenge and biopsy.  Hang on in there. Sue

      When symptoms like fatigue, brain fog, or low energy change how we interact, others sometimes misinterpret that as disinterest, rudeness, or negativity—especially if they don’t understand the underlying condition. That doesn’t make their behavior okay, though. You don’t deserve to be treated poorly for something outside your control. Often, it reflects a lack of awareness or empathy on their part, not a fault in you. It can help to explain your condition to people you trust, but it’s also completely valid to set boundaries and distance yourself from those who respond with hostility. Your experience—and your reaction to it—makes sense. The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron, vitamin D, folate (vitamin B9), vitamin B12, calcium, zinc, and magnesium.  Unfortunately many doctors, including my own doctor at the time, don't do extensive follow up testing for a broad range of nutrient deficiencies, nor recommend that those just diagnosed with celiac disease take a broad spectrum vitamin/mineral supplement, which would greatly benefit most, if not all, newly diagnosed celiacs. Because of this it took me decades to overcome a few long-standing issues I had that were associated with gluten ataxia, for example numbness and tingling in my feet, and muscle knots--especially in my shoulders an neck. Only long term extensive supplementation has helped me to resolve these issues.

      Being HLA-DQ2 positive doesn’t diagnose celiac disease by itself, but it does mean he has the genetic potential for it, so it absolutely deserves careful follow-up if symptoms or concerns are present. You’re right that celiac is often downplayed, but it’s a serious autoimmune condition—not an allergy—and it can affect the brain, nervous system, and overall health if untreated. Given everything your son has been through, you’re doing the right thing by advocating and asking questions. I would strongly recommend getting a full copy of his records, and if possible, consulting a gastroenterologist who understands celiac disease well so you can get clear answers and, if needed, proper testing and monitoring.
