Determining whether a nail has developed a fungal infection or not can be tricky. Often times the nail may simply appear bruised or discolored due to consistent polish use, however there are a number of ways to detect if you have developed a fungal nail or not.
First things first, if you see spotting, discoloration, thickening, and/or brittleness you are likely to have developed nail fungus. It is important to take note of these signs and visit a podiatrist or a doctor if you notice any of the above.
It is quite simple for doctors to diagnose nail fungus. Some prefer the conventional method of taking a sample of the nail and sending it to a lab for a nail culture. This has always been thought to be the most accurate way of determination, however studies have proven that these test often come out 50% false-positive and 50% false-negative, meaning that there is a 50% chance that the result is false. In recent years however, podiatrists are able to detect if an individual has a nail fungus by simply looking at the nail and taking note of a number of factors that indicate a nail fungus.
If you are concerned that you or someone you know has developed a nail fungus, you need to contact a professional immediately for a diagnosis before the fungus worsens and spreads.
