True or False: Urine specimens for Cytological examination should be a first morning catch.

For cytological examinations of urine specimens, it is not necessary for the sample to be a first morning catch. The rationale behind this is that cytological assessments focus on the cellular components present in urine samples rather than on the concentration of analytes, which is influenced by the time of day. Urine collected at any time during the day can provide sufficient cells for examining any abnormalities, such as cancer or inflammation, which are typically the main focus in cytology.

First morning specimens are often preferred for certain tests because they are more concentrated and can yield more information regarding specific substances or conditions, but this is not the case for cytological examinations. Therefore, stating that urine specimens for cytological examination should be a first morning catch is not accurate, making the statement false.
