A wood lamps skin examination is a procedure that detects skin infection using transillumination. Another popular name for this examination is the ultraviolet light test. This procedure can also help examine the skin for other irregularities and skin pigment disorders such as vitiligo. In addition to that, it can also be used to detect if an individual has a corneal abrasion on the eye surfaces.
A wood lamp is a small handheld device that uses light to illuminate specific skin areas. For accuracy, the test is done in a room with no light access. If you have a skin infection, the light color changes as it scans through the affected area. Wood lamp examination works for many different skin issues such as vitiligo, melasma, tinea capitis, pityriasis versicolor, etc.
For those with scratches on the eye, the first thing you doctor will do is to put a fluorescin solution into the affected area. Afterward, the doctor will run the wood lamp over the eye to check for any complications. You will see a bright light color as the lamp shines over the scratches or abrasions. One of the reasons why many people opt for this procedure is that it is safe and risk-free.
Things to Know About Wood Lamp Procedure
Prior to going for the test, it is recommended to wash the affected area. Do not apply any beauty product including perfume or makeup on the affected area before the test. These products contain ingredients that can cause a glow in the skin area applied as the light runs over it. This is in turn results in a misleading result.
The procedure usually takes place in the office of a professional doctor. What’s more, the procedure is safe, easy and completed within the shortest time possible. On getting to the doctor’s office, you’ll have to remove clothing to expose the skin area that will be checked. Then the doctor turns off the light to darken the room and move the wood lamp over the skin to inspect for infections.
How Do You Know If You Have a Bacterial
If your skin is infection-free, the light will look purple, or violet and the wood lamp will not glow as it scans through your skin. If, on the other hand, you have a fungal or bacterial, the light will glow as it reaches the affected area. Normally, some fungi and some bacteria glow when they come across UV light.
Keep in mind that less darkened room as well as applying several skin products on the affected area before the procedure will give a misleading result. Also, it is important to note that the device does not test for all fungi and bacterial infections.
Odds are you may still be infected even though the wood lamp found nothing. In this case, you doctor may need to perform a few lab tests. Alternatively, they can conduct a physical examination to detect any infection. This way, they can provide the right treatment procedure to follow.
