Answer:
The correct answer is: 600,000 years
Explanation:
Half-life is the time which is essential or required to decrease a specific substance to half of its initial amount of the substance. So, if a substance has a half-life of 200,000 years then it means it takes 200,000 years to decrease or change into a new substance and remain half of its initial quantity.
half-life amount
0 20000
1 10000
2 5000
3 2500
total half-life = 3 to 2500 atoms of A
so, the time will be = 3 * 200,000 years
= 6000000

The hiv-1/2 ag/ab immunoassay test identifies the P24 antigen and antibodies that may be present in the blood as early as 13 days post exposure .
<h3>What is hiv-1/2 ag/ab immunoassay test ?</h3>
It is a rapid point care test .hiv-1/2 ag/ab is a solid phase enzyme -linked immunosorbent assay for the qualitative detection of HIV-1 ( P24 antigen) , anti-HIV-1 including subtype O, and anti-HIV-2 antibodies ( including isotype IgG, IgM ,IgA ) in human serum or plasma.
It is the latest generation for the simultaneous detection of the presence of anti -HIV antibodies and HIV antigens . it also helps in the differentiation of HIV-1 from HIV-2 infection .
HIV-1 was discovered first and is more prevalent worldwide , while HIV-2 is less pathogenic and is mostly confined to west africa.
<h3>What is P24 antigen ?</h3>
P24 antigen is the indication of HIV positive .when you do your hiv test then if it found in blood then your body infected by HIV .P24 is produced 2-3 weeks after infection and before antibodies are produced .
P24 levels are only detectable for the next 1-2 months. P24 levels typically peak just after the onset of ARS symptoms at 2-3 weeks after infection .
