Hello, class.
00:01
Today we're going to be discussing about this question in regards to the chapter on immunization and immune testing.
00:10
So for this question, they're asking which one of these choices are required for direct fluorescent anti -testing? is it heat inactive serum or fluorescent serum, immune complexes, or antibodies against the, antigens.
00:31
I'll give you a moment to pause the video and you can choose which one is the right answer and then we'll come back and discuss about the question.
00:42
Okay, if you pause the question, let's go about fluorescent antibody testing.
00:51
So fluorescent antibody testing is basically like fluorescent dyes are used to label in several.
01:01
Serological testing.
01:05
And there were like two different types of ways how the antibodies, like, because that's what they're forensically, they'll label the antibodies are used in direct or indirect fluorescent antibody testing.
01:31
So the direct one is usually just identifies the present of antigens in the tissue while indirect is used to detect the presence of specific antibodies in individual serums...
