There is a simple finger test you can perform at home to determine if you have a major health problem, and it couldn’t be simpler.

It might be difficult to recognize the symptoms of a significant health problem, which is why it’s critical that if you notice anything strange about yourself, you consult with a doctor.

Most people are aware of the more obvious signs, such as lumps, discomfort, or appetite changes, but there are also more subtle signs that something is wrong.

In reality, there is one test you can perform at home, and it is quite straightforward.

Dr. Ahmed, also known as @dra_says on TikTok, demonstrated how to do the Schamroth Window test, which indicates finger clubbing.

The term “clubbed fingers” refers to the appearance of your fingers’ endings.

Clubbed fingers cause the nail to bend down and resemble an upside-down spoon, while the tips swell and may become heated and discolored.

The shift might suggest major issues with the lungs or heart, so if you observe it, get medical attention.

“You can all do this one test at home to see if you’ve got any serious heart or lung problems,” stated Dr. Ahmed, before displaying a comparison of normal and clubbed fingers.

“With clubbed fingers, you get a very round, bulb-like fingertip.” They can be quite white, with a shining foundation to the nails.

Although the precise cause of finger clubbing is unknown, experts currently agree that chronically low oxygen levels are the cause.

“Clubbing is something we carefully look for during a physical examination.

“But it might have terrible consequences. One of the reasons is lung cancer, bronchiectasis, cystic fibrosis, or a lung abscess.

Dr. Ahmed went on to say that a variety of cardiac disorders might cause the fingers to seem clubbed.

Dr. Ahmed advised patients to perform the simple test by bringing the fingertips of their two index fingers together until both nails touched.

Imagine making a love heart symbol with your fingers.

There should be a little window at the base of both fingernails.

“If you think you’ve got finger clubbing, especially if it’s new, you must get it checked out,” stated the doctor.
