Lupus is very difficult to diagnose. It's not easy as 123. There is not a definitive test that can accurately diagnose the disease. Blood tests are not definitive of a lupus diagnosis.. they're only pieces of this puzzle. Lupus is a great imitator which is why it's important to have all other diseases/syndromes ruled out FIRST, once everything else is cleared and you still have symptoms, look at lupus.
A positive RH factor refers to your blood type- A+, O+, etc. Do you mean a positive rheumatoid factor? A positive ANA is a piece of the overall puzzle but a small piece.
A certain percentage of the population has a positive ANA and has no health problems, while you can have a negative ANA and still have lupus.
More important tests are sed rate, crp, complements, autoantibodies, etc.
You need to see a rheumatologist and allow him to figure this out. No other type of doctor really understands lupus and all that it entails (which is a lot!) which you're experiencing right now- with 2 different opinions. You also do not want to use certain types of medications without the right doctor watching over you. Medications for lupus affect your immune system (lupus is an overacti ve immune system so drugs are needed to slow it down) and are serious with potentionally life altering side effects.
It's very common for a diagnosis to take time. In fact, it's also common to see multiple doctors until you get the right diagnosis,
I was diagnosed quickly and it still took around a year.. that was 13 years ago. I'm now 33.. it's been a long 13 years.
If you contact me privately, I can send you some very helpful lupus information.
It's important for your health, that you keep your mind open (to other diseases) yet press your doctors for answers.
One of the best things you can do right now is to keep a health diary- note everything- how you slept, what you ate, how's the weather, did you exercise? what medications/vitamins did you take?, etc, etc. Note everything! Over time, you'll see a pattern. This diary will help your doctors get a better picture of what's going on with you.
It's late so I hope this makes sense. Stay positive and contact me offline if you want to chat.
