Similarly, I would like to know how much a dx (e.g.LupusLupus - resources
Lupus, discoid - view of lesions on the chest
Lupus, discoid on a child's face
Lupus, discoid on the face
Systemic lupus erythematosus
Systemic lupus erythematosus rash on the face) is based on ANA results vs. symptoms. I can't seem to find that.

I'm not sure of a direct percentage perse, but I know it's possible to have LupusLupus - resources
Lupus, discoid - view of lesions on the chest
Lupus, discoid on a child's face
Lupus, discoid on the face
Systemic lupus erythematosus
Systemic lupus erythematosus rash on the face and the serology not confirm it.  So it would stand to reason to me the same could hold true for sclerodermaScleroderma
Scleroderma - resources.  For years, a classmate of mine suffered with all the classic symptoms of LupusLupus - resources
Lupus, discoid - view of lesions on the chest
Lupus, discoid on a child's face
Lupus, discoid on the face
Systemic lupus erythematosus
Systemic lupus erythematosus rash on the face, but her serologies kept coming backBack pain - low
Back strain treatment negative and she was referred to psychology, but she had symptoms they could not ignore. Fortunately, her rheumatologist tried her on prednisone, methotrexate, and Plaquenil intermittently and during those times her symptoms would improve. She was finally diagnosed after a terrible flare when her serologies did come backBack pain - low
Back strain treatment positive. I would suggest retesting intermittently if you know for sure something is going on. These diseases are so hard to diagnose!  

I have been dealing with some type of auto-immune disease for about 6 years.  My original bloodAmylase - blood

Blood clot formation
Blood clots
Blood culture

Blood gases
Blood gases test
Blood glucose monitoring
Blood in semen work was positive for ANA as well as the sclerodermaScleroderma

Respiratory syncytial virus antibodies.  I have never again tested positive for sclerodermaScleroderma
Scleroderma - resources, but my labwork changes all the time.  Sometimes the ANA is positive, sometimes not.  I have seen 5 rheumatologists and they all have different opinions.  I have been on every med available and the only thing that really makes me feel better is prednisone.  
I guess what I am saying is that your lab values can change and you can still have one of these autoimmuneAutoimmune disorders diseases even though the labwork is negative at any given time.  Did they run the sclerodermaScleroderma
Scleroderma - resources test?  I would just find a good rheumatologist and keep trying to find an answer.  Sorry I couldn't help much.  Good luck.

I was just told that I have a positive ANA so they looked for other auto immuneImmune globulin intramuscular
Immune globulin intravenous
Immune globulin subcutaneous diseases other than lupusLupus - resources
Lupus, discoid - view of lesions on the chest
Lupus, discoid on a child's face
Lupus, discoid on the face
Systemic lupus erythematosus
Systemic lupus erythematosus rash on the face (which I am diagnosed as having mildly as well as Raynaulds).  They found PBC (primaryPrimary amyloidosis
Primary biliary cirrhosis
Primary hyperparathyroidism
Primary insomnia
Primary lymphoma of the brain BiliaryBile duct obstruction
Biliary atresia
Biliary obstruction - series
Biliary stricture
Biopsy - biliary tract
Gallbladder disease
Gallbladder radionuclide scan
Primary biliary cirrhosis Cirrosis).  

This may not be so in your case but with the relevent tests, the powers that be will diagnose you accordingly.  Its just that many of the auto immuneImmune globulin intramuscular
Immune globulin intravenous
Immune globulin subcutaneous symptoms display so many of the same or similar charactoristics.

After a majorMajor tears
Major-con flare up and finding that I also had a positive AMA, it was found that I also have auto immuneImmune globulin intramuscular
Immune globulin intravenous
Immune globulin subcutaneous hepititis which is quite advances.  This was a complete surprise but I must say that after being given the appropriate meds for this condition, I have not only stabilised but have also been feeling a whole lot better for now.

No one knows how long this will last but the consultants are vigilant and once they are on your case, they will endeavour to crack it!!!

One piece of advise though, it would not hurt to keep a diary of events stating how you are feeling that day, aches, dry eyesAmblyopia
Blepharitis
Bloodshot eyes
Cataract - close-up of the eye
Color vision test
Conjunctivitis
Contact lens electrode on eye
Crossed eyes
Dry eyes
External and internal eye anatomy
Eye, itchingCauses of vaginal itching
Eye burning - itching and discharge
Itching
Jock itch
Muscle twitching
Vaginal itching, night sweatsSweat electrolytes test
Sweat test
Sweating
Sweating - absent, nauseaHyperemesis gravidarum
Morning sickness
Nausea and vomiting, any thing at all.  This information is very helpful to the consultant.
