For any sample requiring cytogenetic studies please clearly write on the request form the gestational age, site of biopsy, and "Cytogenetics Testing". Send the sample immediately to the laboratory. If the sample is also requiring routine histology, ensure a sample for cytogenetics is taken <u>before</u> any formalin is added. If further information is required please contact the Histology department or contact Wellington Regional Genetics Laboratory 04 918 6967. | |||
