See details: There are literally scores of autoimmune diseases. Some can be diagnosed with the help of lab tests and some cannot. Lupus can be present even if all autoantibody testing is negative. However, this is a rare occurrence.
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.See 1 more doctor answer
Blood test result- ANA by EIA=negative. Is this reassuring as far as lupus or other autoimmune problem?
Mostly: 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, your tests are reassuring but do not 100% exclude autoimmune disorders as there are may such disorders that occur without ANA.

What is IgG CMV blood test and what do results say about my health? Can it be indicative of lupus or another infection, disease, disorder, etc.?
Well: A positive test for CMV (cytomegalovirus) IgG indicates that a person was infected with CMV at some time during their life but the IgG test cannot determine when a person was infected. It is a common virus that is usually harmless. However the immunosuppressed can become quite ill. Most people don't even know they have had it.See 1 more doctor answer
See details: Http://www. Ncbi. Nlm. Nih. Gov/pubmedhealth/PMH0041704/ The above link should give you the info. However, if the ANA is negative, the chances of you having lupus is small.
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.See 1 more doctor answer
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.
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.See 1 more doctor answer

Lupus blood tests: Have your physician order an ANA test. If that is positive, seek the care of a rheumatologist. For further tests. Patients with lupus are anemic, usually.
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.See 2 more doctor answers
Yes: However, the chances are fairly low but not zero. See a rheumatologist if you are concerned.
If someone is suspectd to get lupus in later stages i.E 30s-40s.Will his blood test for ANA & antidns b +iv in 10s-20s without disease symtoms.
Need big picture: I understand that you have mouth ulcers, unexplained weight loss, and are taking azathioprine and Plaquenil / hydroxychloroquine; you have a positive ANA at some titer and anti-dsdna. I suspect you have lupus though no one really knows what lupus is and it's defined by criteria; the burning question is whether to treat this aggressively. You deserve a 2nd opinion beyond what we can do. Best 2u.See 1 more doctor answer
Can an ANA test or any blood test used to diagnose auto-immune diseases show all the types of lupus?
Not necessarily: Patients with systemic le will almost always have a positive ana. However, patients with lupus confined to the skin, i.e. Discoid le or scle (subacute cutaneous le)may not have a positive ana. A positive ANA by itself does not necessarily indicate sle and is seen in a number of medical conditions. The diagnosis of sle is made on the basis of historical, clinical and laboratory criteria.See 1 more doctor answer
