How can you tell the difference between gout and pseudogout?
Gout crystals are shaped like a needle and are negatively birefringent. Pseudogout crystals are rhomboid shaped and positively birefingent. X-rays can also be helpful as they show different changes. Gout eats away at the bones and joints of the hand and wrist.
How do you confirm pseudogout?
The most dependable way to diagnose pseudogout is through joint fluid analysis. A doctor will use a needle to extract a small amount of synovial fluid from the affected joint—a procedure called joint aspiration—and send it to a lab for analysis. During analysis, the fluid will be examined under a polarized microscope.
Is pseudogout worse than gout?

What do pseudogout crystals look like?
Pseudogout crystals (CPP) are rod-shaped with blunt ends and are positively birefringent. Thus, pseudogout crystals are blue when aligned parallel to the slow ray of the compensator and yellow when they are perpendicular. Crystals must be distinguished from birefringent cartilaginous or other debris.
Is uric acid high with pseudogout?
In pseudogout, or CPPD, crystals of pyrophosphate dihydrate form in your joints causing pain. Gout, on the other hand, is caused by the formation of monosodium urate crystals due to high levels of uric acid. The crystals form around your joints, causing pain.
What is the most commonly affected joint for pseudogout?
