Attempts to improve the system have mainly been directed toward broad general concerns, with little attention being given to specific problems or issues. A failure to resolve these problems has frequently resulted in increased testing costs and complicat

Although this number is only an approximation of the total number of women in the labor force who were pregnant during that year, it is an indication of the large number of pregnancies potentially at risk from the occupational environment.
