Lupus Cause High Co2 Blood Test
My childs potassium, alkaline phosphate, carbon dioxide are low on blood test. Test was done due to my lupus & hypothyroidism. What does this mean?
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. ...Read more
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)?
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.
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. ...Read more
False positive for Lupus, now positive for HCV, waiting on blood test to confirm. Could HCV cause a false + for lupus?
The result of my blood test for C3 complement is high and CPK result is too low, so do I have lupus?
Incomplete: Information. High C3 is an acute phase reactant and may be elevated in any case of inflammation. CPK is an indicator of muscle damage and there is no value that is too low. Diagnosis of lupus is based on a number of parameters and is a combination of clinical findings and lab tests. Please consult your doctor for a proper evaluation. ...Read more
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?
Negative ANA blood test but positive anti-dsDNA antibodies. Do I have lupus? What causes this? Very symptomatic.
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. ...Read more
Can Diltiazem cause a lupus titer of 1:320? I also have positive ana and homogeneous pattern. All other blood test were normal.
I got my CRP blood test back and it came back high 25.7 mg/l. Lupus and RA are negative. I have a normal CBC also and all other normal test. Any idea?
How high is my risk for blood clot or stroke with Depo-Provera provera (medroxyprogesterone) shot if I have lupus, sjogrens. Is there a clotting blood test I can take to be safe?
Low: Risk is low but it is incased with these conditions esp. With Lupus ...Read more
Random aches migrating around body (muscles/joints). Blood test cleared me of lupus, thyroid, Lyme etc. Doctors think anxiety. Is this a likely cause?
Can late-stage Lyme, EBV, HHV6, or lead toxicity cause a malar rash? Blood test - for lupus. Skin biopsy - for rosacea but + for general inflammation.
Lab results: The lab results you mention, low creatinine high and egfr is low are consistent with a person with chronic kidney disease. The co2 in chronic kidney disease is not high and can be low. The high bun-creatinine ratio is suggestive of a dehydrated state. Please provide the actual numbers of the lab values you stated for a better answer. ...Read more
Wha???: Numbers, numbers, numbers. You need you know the reference ranges of the lab that did the tests. You need to know why the tests were done and how they relate to prior tests, if any. Those numbers on their face don't bother me too much, but that's not really saying too much either. What bothers me is that you didn't ask the doctor who ordered them. So, your mission is clear..... ...Read more
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. Having said that, it may helped to have the actual result and the reason the test was done.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more
Should lisonpril hctz (hydrochlorothiazide) be discontinued if I have had diarrhea since I started taking it 7 days ago. Blood test shows dehydration and elevated co2.
Diarrhea and meds: If you had diarrhea (d), your co2 would be low due to loss of alakli in your stool. Neither lisinopril/ hctz (hydrochlorothiazide) (l) are known to cause diarrhea. If you had d for 7 days, you need to contact your physician (p) or go to the er. I would stop your l, as your blood pressure would be low due to fluid loss seen with d. Is your potassium low? What fluids are you ingesting? Call your p or go to an er for help. ...Read more
Is it possible to have too much co2 in blood test for electrolytes, serum? I got 31 meq/l Does it mean I'm not getting enough o2? My pulse lately high
Not a problem: The CO2 you're referring to (in a venous blood sample) is actually a measurement of "carbon dioxide combining power" and not carbon dioxide. It indicates a mild metabolic alkalosis. In an outpatient population, the most common cause is mild volume contraction. If you drink a liter of water, wait a couple of hours, and repeat the test, it will likely normalize. Your kidneys regulate this. ...Read more
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?
CO2 in the blood: This can have many causes, such as from COPD if it is chronic, in order to know what to do about the lab abnormality we need to know why it is abnormal. Sometimes an "abnormal" lab is simply a lab error. More information is needed to properly answer the question. ...Read more
If you is tell by your doctor just buy a blood test that you might have lupus what else could it be?
Many factors: Nobody really knows what lupus is, but making the diagnosis is crucial and lives depend on it. Bloodwork is one component along with other clinical features. The usual screen is the anti-nuclear antibody assay which picks up the vast majority of cases, though most people with positive ANA do not have lupus. Ask the titer, pattern, follow-up labs. ...Read more
What is the likelihood of a false negative herpes type specific blood test with background of lupus (sle)?
About 0% to 9%: Quest diagnostics' website states that their herpes type-specific IgG antibody test is 91-100% sensitive, so there are a few false negative results. A repeat test can be done 4-6 weeks later, if worried about a false negative. Lupus should not affect the result, but if a person is on strong immuno-suppressive therapy, his antibody production may be blocked, which may make test results unreliable. ...Read more
Could you please tell me what blood test are used for lupus. I'm looking at blood test example CBC =blood count. Lupus=?
Yes: There is a simple blood test for lupus called an "ana" (for antinuclear antibody). It is positive, or detectable, in about 20% of healthy people, so it is only helpful as an initial screening. A doctor can ask questions, perform a physical exam and order further tests to figure out if a positive test indicates lupus. A negative test is very reassuring. ...Read more
Yes, but....: Almost all lupus patients have anti-nuclear antibodies in their blood at significant levels, there are other blood tests, but the whole clinical picture needs to be considered before a diagnosis is made, and since no one truly knows what lupus is, some people carry the diagnosis of "borderline / questionable" lupus, and may or may not get treated. ...Read more
Yes: However, the chances are fairly low but not zero. See a rheumatologist if you are concerned. ...Read more
