Question

From which of the following techniques early detection is not possible.
$a$. Serum analysis
$b$. PCR
$c$. ELISA
$d$. Urine analysis
$e$. Recombinant DNA technology

• A. $b, c$ and $e$
• B. $a$ and $d$
• C. $a, d$ and $e$
• D. $b$ and $c$

Answer 1

Answer: (B)

• For effective treatment of a disease, early diagnosis and understanding its pathophysiology is very important.
