How can you use “seropositive” in a sentence? Here are some example sentences to help you improve your vocabulary:
Newkirk et al . also observed that the frequency of autoantibodies to each of the antigens occurred more frequently among CMV seropositive subjects than among CMV seronegative subjects [ 14 ] . For CMV seropositive subjects, they observed that 42 (84%) subjects had antibodies to RNP, 32 (64%) had antibodies to Sm, and 23 (46%) had antibodies to U1-70 kD [ 14 ] . If Newkirk et al . used a negative/positive cutoff value of the mean plus three standard deviations then, overall, less than 10% of their sera contained autoantibodies.
The present study was designed to confirm the report of Newkirk et al . They reported that, among the sera of 100 normal healthy adults (50 CMV seropositive and 50 CMV seronegative), 54% contained antibodies to RNP, 50% contained antibodies to Sm, and 33% contained antibodies to U1-70 kD [ 14 ] .
For Sm, using the mean OD plus two standard deviations (Table 1) of the 40 CMV seronegative sera to establish a negative/positive cutoff value, none of the 40 CMV seropositive sera were positive, one of the CMV seronegative sera was positive (OD = 0.422), and none of the sera from the vaccine recipients were positive.
For example, testing of nearly 700 sera will be required to determine whether an autoantibody frequency of 5% among CMV seropositive individuals and of 1% among CMV seronegative individuals is a significant difference.
With regards to antibody to U1-70 kD, which may be a more sensitive indicator of autoimmune disease, the sera from only one CMV seropositive subject contained these antibodies and none of the sera of the vaccinees contained these antibodies.
