- More than 85 per cent of human beings have Rh+ blood, while the remaining have Rh− blood.
Which of the statements given above is/are correct?
Answer:
Only 2
Notes: ELISA is predominantly used for detecting antibodies related to infectious diseases like HIV, not as a first-line cancer detection method.
