Study Notes
Laboratory Procedures and Timing
- Amniotic fluid request is typically made as soon as cells arrive in the laboratory for processing.
- A specimen is observed to determine cell attachment status and timing for further testing.
Timing for Amniotic Fluid Request
- If no cell attachment is observed, wait 10 days before requesting amniotic fluid for further analysis.
Culture Failure Causes
- Culture failure can be caused by various factors, excluding transport at room temperature, which does not necessarily lead to failure.
- Potential causes of culture failure include:
- Sample exposure to excessive heat (e.g., 40°C).
- Improper sterile techniques during sample collection or handling.
Cytogenetic Study Cell Selection
- For long-term serial cytogenetic studies, fibroblast cells are preferred due to their ability to proliferate and maintain genetic integrity over time.
- Other cell types, such as epithelial cells or lymphocytes, may not provide the same longevity and reliability for cytogenetic testing.
