  1. *Laboratories were identified by the number of specimens submitted. To safeguard anonymity the laboratories in Table 1 have no abbreviation, and the sequence of the laboratories in Tables 1 and 2 has been changed. Despite the loss of relevant information, this approach was necessary since non-anonymity might have discouraged laboratories from participating.
  2. +A national standard, set by the Austrian Society of Cytology, requires that the category Pap 0 should be less than 2% of all smears taken (15).
  3. **no data available;
  4. Laboratories failing to meet the quality criterion are written in bold.
