Consider the following statements: 1. ELISA test is employed as the first and most basic test for an individual to detect cancer. 2. Almost 50% of human beings have Rh+ blood while the remaining have Rh- blood. Which of the statements given above is/are correct?

1. Statement 1 is incorrect. The ELISA (Enzyme-Linked Immunosorbent Assay) test is primarily used to detect antibodies or antigens and is widely employed as a screening test for viruses like HIV, not generally as the first and most basic test to detect cancer. Cancer detection involves various methods like imaging, biopsies, and specific biomarker tests depending on the suspected type. 2. Statement 2 is incorrect. The distribution of Rh factor in human populations varies, but globally, a large majority (around 85% or more in Caucasian populations, higher in others) of human beings have Rh+ blood. The percentage of Rh- individuals is significantly lower than 50%. 3. Therefore, neither statement 1 nor 2 is correct.
