In brief: Skin biobsy ,Flake

There are no lab tests or blood tests available to confirm or deny the presence of psoriasis.
Instead, a doctor must examine the skin and nails closely, sometimes analyzing dry skin under a microscope.Your doctor may take a small sample of skin (biopsy) that's examined under a microscope to determine the exact type of psoriasis and to rule out other disorders.
