  • Karyotype

About this test

Three reasons the Karyotype test is right for you

  • This genetic test analyses the number, size, and structure of your chromosomes to detect abnormalities

  • It helps identify genetic conditions, such as Down syndrome, Turner syndrome, or other chromosomal disorders

  • Results support family planning, fertility evaluation, and diagnosis of unexplained developmental or reproductive issues

What is the Karyotype test?

The Karyotype test examines your chromosomes in detail, looking for missing, extra, or structurally altered chromosomes. Chromosomes carry your genetic information, and abnormalities can impact growth, development, fertility, and overall health.

This test is often recommended for:

  • Individuals or couples experiencing fertility issues or recurrent miscarriages

  • Patients with suspected genetic syndromes or congenital abnormalities

  • Children or adults with developmental delays or unexplained physical anomalies

  • Prenatal assessment when chromosomal disorders are suspected

What are the symptoms or situations that may prompt a Karyotype test?

Indications for karyotype testing include:

  • Recurrent pregnancy loss or infertility

  • Physical or developmental abnormalities in a child or adult

  • Family history of chromosomal disorders

  • Unexplained blood count or congenital anomalies

How does the Karyotype test work?

A blood sample (or in some cases, other tissue samples) is collected and cultured in a laboratory. The chromosomes are stained, photographed, and analysed under a microscope to detect abnormalities in number or structure.

What can I expect at my appointment?

Your appointment involves a standard blood draw performed by a trained healthcare professional. The procedure is quick, minimally invasive, and usually takes only a few minutes.

Analysis of the chromosomes typically takes several days. Your report will provide a detailed chromosomal profile and highlight any abnormalities, helping your clinician guide further investigations or treatment decisions.

Are there any risks with this test?

This is a routine blood test for genetic analysis and is very safe. Most people experience only mild discomfort during the blood draw.

Minor bruising or tenderness may occur at the site, but serious complications are extremely rare.
