In a prospective study controlled experimental variation was introduced in composition of fixative, relative humidity, temperature and airflow during slide preparation from primary CVB and AF <jats:italic>in situ</jats:italic> cultures. For evaluation, analysis of regression or variance was used.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Provided that at least 0.8 mL AF per culture dish was admitted, none of the investigated factors appeared as critical resulting in unacceptable variation in outcome. Variation in appearance of the AF had a relatively major impact: bloody or brown AF resulted in a 3 days longer culture time.</jats:p><jats:p>To a limited degree, metaphase quality of AF and CVB cells was affected by composition of fixative, relative humidity, ambient temperature and airflow during slide preparation.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>Current prenatal cytogenetic practice as described here appears in general to be robust and reliable. The investigated conditions are not critical within the investigated range. Expensive measures for fine control of these conditions are, therefore, not required.
