Karyotyping - Peripheral Blood for Couple

Karyotyping is a diagnostic test that examines the number and structure of chromosomes in a sample of cells. This test is especially significant for couples who have experienced repeated miscarriages, fertility issues, or have a child with a genetic disorder. It helps to detect chromosomal abnormalities, which might be the underlying cause of such complications.


  • Test NameKaryotyping - Peripheral Blood for Couple
  • Sample TypeBlood
  • Preparations RequiredNo special preparation is necessary prior to blood sample collection.
  • Report Time10 Days

The human body typically comprises 46 chromosomes, 23 inherited from the mother, and 23 from the father. Occasionally, errors occur during cell division, leading to an abnormal number of chromosomes or structural changes within the chromosomes. Karyotyping analyzes the chromosomes in a blood sample to identify any such anomalies.

Frequently Asked Questions

Karyotyping is performed to detect chromosomal abnormalities that might contribute to recurrent miscarriages or fertility problems. The test can also determine if you or your partner carries a chromosomal alteration that can be passed on to your children.

The test involves a simple blood draw from the arm of each individual in the couple. The sample is then sent to a laboratory, where technicians will analyze the structure and number of chromosomes.

No, fasting is not required for this test. You can eat and drink normally before the test.

No specific preparation is necessary for this test.

This test is generally recommended for couples who have experienced recurrent miscarriages, fertility issues, or have a child with a genetic disorder. It's best to discuss with your doctor about when this test would be appropriate for you.

The test measures the number and structure of chromosomes in the blood cells. Any anomalies in the number or structure could indicate potential chromosomal disorders.

The frequency of this test is dependent on your medical history and the recommendation of your doctor. Typically, it is only done when there is a clinical indication.

The normal karyotype for a human female is 46, XX, and for a human male is 46, XY. This means females have two of the same kind of sex chromosome (XX), while males have two distinct sex chromosomes (XY).

There are no specific precautions to be taken after the test. You can resume your regular activities immediately.

Technical errors, maternal contamination, or a poor-quality sample can affect the test results. However, these factors are rare and the test is generally reliable.

If the test results are abnormal, you should consult with a genetic counselor or a medical geneticist. They can help you understand what the results mean and what steps you should take next.

The risks associated with this test are minimal and are similar to those of any regular blood draw. These may include slight pain or bruising at the injection site.

A carrier of a genetic disorder is a person who has one copy of a gene mutation associated with the disorder but does not exhibit symptoms. Carriers can, however, pass on the gene mutation to their children.

Yes, this test can help identify if you or your partner are carriers of certain genetic disorders. Knowing your carrier status can provide valuable information about the risk of having a child with a specific genetic condition.

No, lifestyle factors do not generally affect the results of a karyotype test as it assesses the genetic makeup, which remains constant.

No, karyotyping primarily detects large, structural changes in chromosomes. It cannot identify small mutations in the genes that may lead to genetic disorders. For detecting specific genetic disorders, more precise tests, like gene sequencing or molecular genetic tests, may be required.

Yes, karyotyping can be performed during pregnancy using procedures like amniocentesis or chorionic villus sampling (CVS). These tests involve collecting cells from the amniotic fluid or placenta, respectively, to check for chromosomal abnormalities in the fetus. However, these procedures carry a small risk of miscarriage, so they are typically offered when there is an increased risk of genetic disorders.

Yes, karyotyping can determine the sex of the baby. Females typically have two X chromosomes (46, XX), and males have one X and one Y chromosome (46, XY).

A chromosomal translocation occurs when a piece of one chromosome breaks off and attaches to another chromosome. This can result in various health and developmental problems, depending on the chromosomes involved and the specific genes affected by the translocation.

Yes, karyotyping can help in understanding the cause of infertility in some cases. Certain chromosomal abnormalities can lead to recurrent miscarriages or infertility.

Karyotyping is an essential tool in the field of genetics and can provide valuable insights into many health conditions. Although the test results can be complex, working with your healthcare provider and a genetic counselor can help you understand what the results mean for you and your future offspring. It's a significant step towards the path of informed decision-making regarding family planning and genetic health.
