I have had psoriasis for over 50 years but my lab tests are negative. I have symptoms, why are tests negative?

RA factor and Gout negative, CRP within limits, but on high side. These were drawn after the flare had improved. I'm just wondering if a rheumatologist could diagnosis with negative labs

Hi kstone101,
My rheumatologist said to me at my last appointment that you can still have/be diagnosed with PsA if your blood results are negative. I am actually due to see him again in two weeks so I'll try to get his thoughts on why we have symptoms even if the blood results are "normal". I have to say I have always wondered about this too - thanks for bringing it up!
Have you had any imaging tests done? Sometimes these can pick up on inflammation that isn't showing in the blood tests.

Hi kstone,
ALL of my inflammatory markers came back within the standard range. RA factor, SED, Protein, CRP, etc. I was diagnosed with PsA based on MRIs and the pitting in my nails. And it turned out to be the correct diagnosis because my pain went away just a day after my first Humira injection. There were times when i wondered if I REALLY had PsA based on my lab work but PsA is tricky. Your blood doesn't always tell the full story.

Its taking me years to get diagnoised all my previous Doctors and Rheumotologist included kept telling me all my pain was from overuse ....no it wasn't after I had thyroidectomy 18 months ago (cancer) my PSA went into over drive I have Achilles tendonitis in both feet to clearing up overnight on one foot to having the other foot torchure me for over 18 months I currently have tears in my tendons from being medically mistreated. Very disappointing and now after knee surgery another torn tendon (not injury related) I think PSA has invaded my knee is crippling and not much mobility happening and physical therapy going real slow.
