Blood Supply Safety
Last March the Center for Disease Control and Prevention commented on
questions about safety the US blood supply, Here is some of that information:
The
CDC reports that since March 1985 blood donations are required for the antibody
to HIV-1 for HIV-2 since June 1992 and beginning in August 1995 for HIV-1
by an additional test, a P24 antigen test which can detect HIV-1 a week
before the HIV antibody develops.
The
risk for HIV transmission with the current screening, is 1 in about 450,000
to 1 in 600,000 donations infectious for HIV but do not test positive by
currently available HIV antibody tests.
On
Guam, GMH pathologist, Dr. Philip Dauteman, is confident about the antibody
and antigen testing conducted on donated blood at GMH. Newer tests have
shortened the window period where earlier tests wouldn't identify HIV so
that tests now will show HIV infection acquired as recently as 30 days ago.
Those
who do not know their HIV status should have it tested at Public Health
or a private clinic before donating blood. According to the enters for Disease
Control and Prevention, people at risk for HIV infection should not donate
blood.
Antibody
testing at recommended intervals by a HIV counseling and testing site is
the best way for health care providers to routinely diagnose HIV in adults
and children over 18 months.
