And for my money, the best show in TV's greatest decade was Lost in Space. It's impossible to describe what watching this show was like in the 1960s. It's an experience that simply can't be re-produced today.
The reaction reaches its peak about 48 to 72 hours after the PPD is injected. Waiting too long or not long enough may cause an underestimation of the reaction and, therefore, affect how the test is read.A positive test will cause redness, itching and a raised, hardened area of skin called an induration.
How long do results take? Rapid HIV tests can give results in 15â60 minutes, or on the same day. âRapidâ refers for the time taken for the results and not the time since exposure that a test can be used. If samples are being sent to another lab, results can take a few days or a few weeks. Rapid blood tests put a pin-prick of blood on a testing strip. This test takes about 15-20 minutes so you can get the results whilst you wait. Some rapid tests also work on oral samples rather than blood.
