Do I Need a Blood Test for Psoriasis Diagnosis?

Oh dear, here we go again. You think you can just skip a step and save a bit of time and money, don’t you? Well, let’s talk some sense into this plan of yours. First of all, when it comes to psoriasis, a blood test isn’t the magic ticket you might be hoping for. Psoriasis is typically diagnosed by a healthcare professional through a visual examination of your skin. In some cases, if the dermatologist isn’t entirely sure, they might take a biopsy. That’s a small sample of skin, dear, not something you’ll find in a standard blood test.

Now, I know you’re eager to get everything sorted out in one fell swoop, but running off to get a blood test before your appointment might not be the best use of your time or money. Sure, some folks have mentioned checking vitamin D levels because they can be low in people with autoimmune diseases like psoriasis. But hold your horses! It’s best to consult with the dermatologist first. They are the experts, after all, and they’ll know exactly what tests are necessary based on your specific situation.

And while we’re at it, if you’re worried about prescriptions like biologics or injections, remember that these need specific tests ordered by your doctor, possibly including X-rays to check for latent tuberculosis. You see? It’s not as simple as just ticking a box on a form for a blood test.

So, my advice is to sit tight and let the dermatologist guide you. When you do get that appointment, they can determine if any particular tests are needed based on what they see and your health history. Patience is key here! Now, go book that appointment and take care of yourself properly.
