Microneedle patch set to replace standard TB skin test

This test is painless and easier to administer than the traditional skin 

test with a hypodermic needle.

A team of researchers has developed a patch with tiny, biodegradable needles that are
able to penetrate  the skin and precisely deliver a TB test.

Senior author , said that with a microneedle test there’s little room for user error, because
the depth of delivery is determined by the microneedle length rather than the needle-
insertion angle. He said that this  test is painless and easier to administer than the
traditional skin test with a hypodermic needle

Researchers say that their test is going to be easier to use, less painful and has the
potential to be more successful than the standard TB skin test.

The researchers tested the patch on guinea pigs and found that after the microneedles
were inserted using the patch, the skin reaction associated with having a tuberculosis
infection was the same as when using the standard hypodermic needle test.

He said that a microneedle patch test has potential as a simpler, more reliable option than
the traditional tuberculosis test for children who are needle-shy, or in developing countries where medical care is limited.

He added that it’s like putting on a bandage, as long as the patch is applied on the skin,
the test is always delivered to the same depth underneath the skin.
