It seems there are $5 DNA tests and several programs to get them deployed. Plus there are cheaper, faster and more sensitive tests on the way. Perhaps there are some situations where they will not work ?

http://www.voanews.com/english/archive/2008-07/2008-07-01-voa6.cfm?CFID=298056391&CFTOKEN=65066583&jsessionid=8830485addef8d1612791a3c516b1a462433

In 2008, The World Health Organization and a number of global health partners announced the $26.1 million initiative to begin converting laboratories in more than two-dozen of the poorest nations from molecular-based testing to genetics testing for tuberculosis.

The DNA test, called a "line probe assay," could tell clinicians within a day whether someone is infected with a strain of tuberculosis that is resistant to the more common antibiotic drugs so more aggressive therapy can be started.

Current TB tests involving a culture can take weeks to months to process, at a time when the number of cases of multi-drug resistant tuberculosis, or MDR-TB, is growing.

Rick O'Brien is head of project evaluation for FIND, a Geneva-based organization that developed the rapid TB test for clinical use and is now helping countries to prepare to use the new laboratory technology.

"We see this test as having the potential to revolutionize the diagnosis of MDR-TB and make a significant contribution to controlling this expanding and critical epidemic," he said.

The initiative follows field trials of the DNA test in South Africa which showed that it performed as well or better than the old-fashioned method of diagnosing TB with a microscope.

Officials says each DNA test costs an average of five dollars, and it takes about one week to train a laboratory technician. A pilot project was conducted in Lesotho, which officials say now has a state-of-the-art laboratory system.

Hoping that you can find the solution

Seems like your CAPTCHA is no longer protecting you from auto-spammers.

Sharon, Papers Research, and Linear Actuators are likely all bots...or at best 3rd world wage slaves entering CAPTCHAs for bots.
