What is the next step if there are not enough metaphases to complete a cytogenetic study?

When faced with the situation of inadequate metaphases to complete a cytogenetic study, the most logical and effective next step is to prepare additional slides from the remaining samples. This approach allows for the potential identification of more metaphases, which are crucial for karyotyping and chromosome analysis. By preparing additional slides, you maximize the chance of capturing enough cells that can be analyzed, thus ensuring that a comprehensive assessment can be made.

Requesting a new sample from the patient can be a more complex and time-consuming process, and may not always be feasible depending on the circumstances and patient conditions. Conducting a different type of analysis may not provide the specific chromosomal information required if the goal is to perform a standard cytogenetic study. Meanwhile, reviewing previous results for comparison may be useful in some contexts, but it does not directly address the immediate need for more metaphases for the current study. Preparing additional slides is a proactive and efficient step in this scenario.
