However, it may not detect very small genetic alterations or mutations at the molecular level. Despite this limitation, it remains a reliable method for identifying major chromosomal issues.
What is the difference between this test and advanced genetic tests like microarray?
Karyotyping focuses on analyzing the overall structure and number of chromosomes, making it suitable for detecting large abnormalities and balanced rearrangements. Microarray testing, on the other hand, examines DNA at a higher resolution and identifies smaller changes such as microdeletions and microduplications. While microarray offers more detailed analysis, it cannot detect balanced chromosomal rearrangements, which makes karyotyping an essential complementary test in many cases.
Why might a doctor recommend this test?
A doctor may recommend this test when there are clinical signs suggesting a chromosomal condition, such as growth issues, developmental delays, or reproductive problems. It may also be advised in cases of repeated miscarriages, abnormal hormone levels, or unexplained medical symptoms. The test helps identify underlying genetic causes and supports accurate diagnosis and treatment planning.
How long does it take to receive the results?
The turnaround time for this test usually ranges from 10 to 21 working days. This is because the cells need to be cultured and prepared before chromosomes can be analyzed. The process requires precision and careful observation, followed by interpretation by experienced professionals. The final report provides detailed information about the chromosomal findings.
What does a normal result indicate?
A normal result indicates that the individual has the typical number and structure of chromosomes, with no detectable abnormalities. This suggests that chromosomal factors are unlikely to be responsible for the individual’s condition. However, it is important to note that a normal result does not rule out all genetic disorders, especially those caused by small mutations or gene-level changes.
What happens if an abnormality is detected?
If the Karyotype – Peripheral Blood (Single) test identifies a chromosomal abnormality, the findings are explained by a genetic specialist who will discuss their significance and potential impact on health.
