WinRho SD may also be prescribed for the suppression of Rho (D) isoimmunization, which occurs principally when a woman with an Rh negative
blood type becomes pregnant with a Rho (D) positive fetus.
The NHS is appealing for O Rh negative
(O-) and B Rh negative
(B-) blood donors to come forward now.
Its projected August inventory of below 5,000 pints of blood, and little RH Negative
blood available, is a very dangerous situation for our hospitals and can dramatically impact the quality of patient care delivered," noted Kenneth E.
