Since only 16 of these patients had presented for laboratory investigations within a week of the onset of symptoms, the value of haemagglutination-inhibition tests was considerably reduced; the diagnosis in these cases was confirmed by complement-fixation and rubella-specific IgM tests.<\/jats:p>\n                  <jats:p>Of 172 patients exposed to a rubella-like illness, only 17 were seronegative; 105 sought advice within two weeks of exposure, and therefore the haemagglutination-inhibition antibody tests were useful in determining immunity. Since the clinical diagnosis of rubella was proved incorrect in a number of cases, these pregnancies were saved. Hence both doctors and patients should report both exposure to and rubella-like illnesses as early as possible, so that laboratory investigations may be carried out without delay.<\/jats:p>","DOI":"10.1136\/bmj.3.5717.247","type":"journal-article","created":{"date-parts":[[2009,4,2]],"date-time":"2009-04-02T07:02:10Z","timestamp":1238655730000},"page":"247-250","source":"Crossref","is-referenced-by-count":21,"title":["Serological Assessment of Rubella During Pregnancy"],"prefix":"10.1136","volume":"3","author":[{"given":"J.
