What Tests Do Dermatology Diagnostic Labs Perform?

Are you visiting your dermatologist to have a discolored and oddly shaped blemish on skin checked by the doctor?  Do you have a family history of melanoma or other skin diseases?  These are common reasons why you may want to visit your dermatologist on a regular basis.  Anytime you go to the dermatologist with existing and curious symptoms, they may take a skin sample to send to their dermatology pathology lab in Tampa, where it will be tested for diagnosis and illness detection.  In our lab facility, we work heavily with skin samples to ensure that patients get the right diagnosis and treatment they deserve.  There are a few tests that are commonly performed in dermatology pathology labs like ours.


Skin biopsies are the most commonly known test that can determine skin disorders.  These can be done using a variety of methods, such as punch, wedge excision, or shave.  Shaving is used to remove any lesions that are on the outer layer of the skin.  By using a razor, the doctor can remove a few cells that are sent for further testing.  Punch biopsies involve a tube that is inserted into the skin to remove a few cells at the base of the issue.  Wedge excision involves using a scalpel for deeper biopsies.

Scraping Tests

Scaping can be done when there are issues on the outermost layer of the skin.  This is commonly done to diagnose fungal infections or scabies.  These skin cells are then placed under a microscope with certain solutions in order to detect fungal growth or mites or eggs.  

Light Tests on Lesions

Wood light is used to determine the extent of lesions on your skin.  This can distinguish the pigmentation of the skin, which provides specific information about the borders of the lesion.  Certain infections, like those that are caused by burns, can be detected using this test.  The sample will turn a certain color, therefore indicated the extent of infection.

Tzanck Tests

This type of test is commonly used to diagnose viral diseases, like herpes.  They will take a closer examination at the blisters on the skin, which they remove with a sharp blade.  During this test, they will look at the skin scrapings to determine whether the infection is viral in origin.  When they add a certain stain and look at the slide under a microscope, the technicians will be able to determine the infection.

These are just four of the many types of diagnostic tests we can perform to determine skin disorders and diseases.  As an expert dermatology pathology lab in Tampa, we work heavily with many dermatologists in the area to provide them and their patients with reliable and time-sensitive results to their tests.  Contact us to hear about the range of diagnostic services we offer our medical partners today.
