Question 1

blood test 2 months post-covid shows high chloride (108mmol/l), high co2 total (32mmol/l) and low anion gap (3mmol/l). cbc, glucose, na, creatinine, etc all normal. sporadic sinus tachycardia. waiting on ecg/echo results. further testing recommended?

Accepted Answer

: Wait for the echo results. If you are otherwise symptom free, there appears to be no major issues

Question 2

my childs potassium, alkaline phosphate, carbon dioxide are low on blood test. test was done due to my lupus & hypothyroidism. what does this mean?

Accepted Answer

Hard to say: Random test results reported with no  history or exam findings make it impossible to decide if they are important or not. The normal values vary sometimes by age and we don't know if the report used proper kid or adult standards.You should review these with whoever ordered them.

Question 3

71, former smoker, had a cat scan recently due to high co2 (32) in my lab test. no sleep apnea (tested). other cause? my blood pressure med (hctz)?

Accepted Answer

It is the HCTZ (hydrochlorothiazide): Hctz (hydrochlorothiazide) causes intravascular volume depletion and elevated co2.  Discuss with your pcp to change it and no need for any testing.

Question 4

can lisonpril cause slight elevated co2 levels? i was on it for a week.blood test showed slight dehydration and slight elev co2. had diarrhea also.

Accepted Answer

Electrolytes: It is more likely that the diarrhea did this than the lisinopril.  Presumably your kidneys are normal (normal creatinine).

Question 5

what would cause a teenager to have high co2 results in blood work?

Accepted Answer

Hypercapnea: There are multiple reasons why a person may have high co2 in a venous sample.  The must common cause would be dehydration. But, once he is well hydrated, if the bicarbonate (sodium bicarbonate) remains high, the patient needs a work up for it since there are other metabolic diseases associated with an abnormal bicarbonate (sodium bicarbonate) that need to be address.  The list is too long to be answer in this format.

Question 6

had crp blood test said normal was 0-10 and mine was 12.4 is this high or just slightly elevated and means nothing? having work up for lupus or ra

Accepted Answer

Not diagnostic : CRP (C-reactive protein) is a protein that is increased in diseases in which there is inflammation. A slightly increased level of CRP is compatible with both sLE and RA, but is NOT diagnostic of either. Furthermore, there are many other causes of such a small elevation of CRP.

Question 7

the result of my blood test for c3 complement is high and cpk result is too low, so do i have lupus?

Accepted Answer

No: To diagnose sle there are several criteria (at least 4 of them) that the patient must meet. C3 complement and CPK are not included in those criteria.

Question 8

the result of my blood test for c3 complement is high and cpk result is too low, does this mean i have symptoms of lupus?

Accepted Answer

No: High C3 is not expected in lupus. More likely it could be normal or low. CPK is high in some connective tissue diseases such as poly myosotis, dermatomyositis, and overlap syndrome of myosotis and lupus. It most definitely is not low.

Question 9

false positive for lupus, now positive for hcv, waiting on blood test to confirm.  could hcv cause a false + for lupus?

Accepted Answer

Yes: False positive test for ANA can occur with viral infections ( hepatitis, parvovirus) , aging, medications (prescription, OTC)  etc.

Question 10

negative ana blood test but positive anti-dsdna antibodies. do i have lupus? what causes this? very symptomatic.

Accepted Answer

Rheumatologist: This test alone is insufficient to diagnose lupus. It has to be supplemented with appropriate symptoms and physical findings. A rheumatologist is best qualified to evaluate, advise, and treat you, if needed.
