Karyotype **

A karyotype is like a detailed map of all the chromosomes in a cell. Everyone has 46 chromosomes, arranged in 23 pairs. The first 22 pairs are called autosomes, and they determine most of our traits, like eye color and height. The 23rd pair are the sex chromosomes, which determine if someone is male or female: females have two X chromosomes (XX) and males have one X and one Y chromosome (XY).A karyotype test allows doctors to look at and analyze a person's chromosomes. This helps them find any problems with the number or structure of the chromosomes that can cause health issues, including miscarriage.
Here's what a karyotype test can do:
- Find chromosome problems and diagnose genetic disorders like Down syndrome, Turner syndrome, and Klinefelter syndrome.
- Identify chromosome changes linked to cancers like leukemia.
- Help diagnose infertility or miscarriage related to chromosome problems.

Patient Instructions:
Patients must fast before blood collection.
Adults: Fast for at least 4 hours.
Children: Fast for at least 2 hours.
Infants: Blood should be drawn before the next feeding.

Do not consume soft drinks, coffee, or any beverages containing sugar; only plain water is allowed.

Within 1 month prior to the blood draw: Do not be under any medication (except for essential medications that cannot be discontinued), especially avoid: antibiotics, traditional herbal medicine.

Notes to the nurses:

- Store and transport the sample at 2–8°C and send it to the laboratory within 12 hours.

- The Karyotype test is performed using the blood culture method, so there is a possibility of culture failure. If the culture fails, the laboratory will notify for sample recollection after 12–15 days.

+ If the first culture fails (no cells or very few cells), the patient will need to provide a second sample to repeat the test. The second sample should be collected at least 1 month after the notification of the failed sample.
+ If the second test still shows no cells (culture failure), no refund will be provided. The patient will be scheduled to repeat the test after 3–6 months, and the third test will be charged at the original test fee.
+ If the first blood culture fails and the patient refuses to provide a second blood sample, no refund will be issued.
