Question 1

hi, i recently had blood work that indicated co2 at 31mmol/l and anion gap at 7.  given that i'm slightly high co2 and low end anion, do i have issue?

Accepted Answer

High tCO2: make sure your potassium is normal
I would repeat it in a week and make sure they are closer to normal

Question 2

had blood work done and anion gap is 18. is this high? the lab defines this in normal range. is it? why do different labs have different normal ranges? if high what should i be looking for?

Accepted Answer

AG: 18 is high. Normal AG is 10-12, it is your measured albumin times 3. What was your bicarbonate (sodium bicarbonate) ? Do you have a medical history of any illness. If not then this can be a processing error and you may need a fresh sample drawn. Suggest look at the whole lab and discuss with the MD that ordered it. If you have no medical issues simply rpt it.

Question 3

my son had blood work completed. the anion gap is 2. he is 7 and does have ulcerative colitis. should i be worried about the anion gap being low?

Accepted Answer

Low anion gap: Anion gap can be low due to decreased albumin in the blood. High plasma IgG can also be the cause of low anion gap. Need to followup with doctor who ordered labs to determine if albumin was also examined.  Review full panel of lab tests with the doctor who ordered labs.

Question 4

anion gap of 14 the rest of my blood work came back fine dr isn't concerned. excerise mildly no symptoms  except a gassy feeling not on any meds ok?

Accepted Answer

Anion gap 14: Anion gap examimes possible acid accumulations. Anion gap of 14 is minimally elevated.  If serum CO2 is less than 22, then more evaluation is needed. Perhaps a repeat chem panel fasting in the morning is best.

Question 5

what could cause a neg anion gap on blood test w low albumin and low tot protein? seen it on blood work over the past year. have ruq pain no diagnosis

Accepted Answer

Reason for concern: You have low Albumin and protein, this is not a matter that should go unexplained. You are either not producing enough Albumin or you are loosing proteins too fast. You should have a diagnosis, you doctor should figure it out.

Question 6

is an anion gap of 14 (ref range: 0-12) worth following up on? the only other abnormality was low vitamin b12 (141 pg/ml). blood work was done due to mood changes (anxiety)?

Accepted Answer

: If you feel physically well and healthy dont do anything except lead a normal life with good diet, exercise and anxiety by keeping busy, meditation, music, sports, social work etc.

Question 7

blood work results ,chloride was low at 98 mmol,anion gap was high at 17.4 ,glucose was high at 108 mg/dl,  a1c was 6.2 ,albumin/globulin ratio  2.0?

Accepted Answer

Prediabetes: Hi. That A1c is above normal, &amp; if that glucose is FASTING, it is too (it's not abnormal if it's not fasting). They demonstrate "prediabetes", the abnormal state between normal &amp; diabetes. What was your bicarb/total CO2? Unless it was low, anion gap (a calculated value) doesn't mean anything; it's useful in states of ketoacidosis, lactic acidosis, etc). A:G ratio is fine too. Eat healthy, exercise

Question 8

low wbc 3, low anion gap 6, and low ig m 47. all other blood work normal so far.  i have discoloration around both eyes. extreme fatigue. blood and bone cancers run in my family. does this point in the direction of multiple myeloma?

Accepted Answer

Need more info: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, multiple myeloma is extremely rare at your age.    Wish you good health!

Question 9

is anion gap test from blood or urine just curious?

Accepted Answer

Blood: It's of zero value in urine, which is loaded with sulfates and phosphates and urates and whatever else.

Question 10

what can a very low anion gap number mean from a blood test?

Accepted Answer

: The most common cause in outpatient care setting is either high serum immunoglobulin and/or low albumin. Lab error is not an uncommon cause. Take care.
