If you’re looking for ways to scrounge up extra funds, the medical industry offers some outlets that might be worth looking into. While these methods of scrapping together supplemental income aren’t for everyone, they might become attractive given the right circumstances.

Money Crashers suggests several methods, including:

* Donate plasma. If you’ve got a couple hours to burn, you can stop by a plasma donation center, answer some questions about your health and activities, and then swap some plasma for cash. If you fear needles or the sight of blood, stay away.

* Participate in studies. Researchers pay out nominal fees for your participation in their work. Studies usually set parameters based on any imaginable criteria, but there’s usually plenty to choose from. If you’re interested, browse college bulletin boards or check out Craigslist or other classified ads.

* Donate sperm or eggs. This is a particularly lucrative outlet, especially for women, but donation isn’t an option for everyone. Those who seek to contribute baby-making materials must pass extensive screenings for factors including age, health and myriad other qualities.
