KARYOTYPING - PERIPHERAL BLOOD FOR COUPLE

Karyotyping – Peripheral Blood for Couple is a specialized genetic test performed on both partners to evaluate the number and structure of chromosomes. This test helps identify chromosomal abnormalities that may contribute to infertility, recurrent pregnancy loss, repeated IVF failure, congenital abnormalities, or reproductive difficulties.

Human cells normally contain 46 chromosomes arranged in 23 pairs. Structural changes, missing chromosomes, extra chromosomes, or balanced chromosomal rearrangements can affect fertility and increase the risk of miscarriage or genetic disorders in offspring. Karyotyping provides a complete visual analysis of chromosomes and helps detect these abnormalities.

The test is performed using a peripheral blood sample collected from both partners. White blood cells are cultured in a specialized laboratory, and chromosomes are analyzed under a microscope by trained cytogenetics experts. The resulting chromosome profile, known as a karyotype, helps determine whether either partner carries a chromosomal abnormality that could affect reproduction.

This test is frequently recommended as part of fertility and reproductive evaluations and provides important information for genetic counseling and family planning.

Benefits of the Test

• Detects chromosomal abnormalities in both partners
• Helps identify genetic causes of infertility
• Assists in evaluating recurrent pregnancy loss
• Supports reproductive and fertility planning
• Helps assess risks for future pregnancies
• Guides genetic counseling and treatment decisions

Why Doctors Recommend This Test

Doctors may recommend Karyotyping – Peripheral Blood for Couple for:

• Recurrent miscarriages
• Unexplained infertility
• Repeated IVF or assisted reproduction failure
• Previous child with chromosomal abnormalities
• Family history of genetic disorders
• Suspected chromosomal rearrangements
• Preconception genetic evaluation
• Reproductive genetic counseling

The test helps identify whether chromosomal abnormalities in either partner may be contributing to reproductive challenges.

Preparation Before Test

The test requires a blood sample from both partners.

• No fasting is required
• No special preparation is usually necessary
• Inform your doctor about previous genetic testing
• Share relevant family and reproductive history
• Follow laboratory instructions for sample collection

The procedure is simple and involves routine venous blood collection.

Normal Reporting Time

Results are generally available within 2 to 4 weeks, depending on chromosome culture growth and laboratory processing requirements.

Who Should Take This Test?

• Couples experiencing infertility
• Couples with recurrent pregnancy loss
• Individuals with repeated IVF failure
• Couples planning pregnancy after a previous genetic abnormality
• Individuals with a family history of chromosomal disorders
• Patients referred for reproductive genetic evaluation

Karyotyping remains one of the most important genetic tests in reproductive medicine and helps identify chromosome-related causes of fertility problems.

Clinical Significance

The test may identify:

• Balanced translocations
• Robertsonian translocations
• Chromosomal inversions
• Numerical chromosome abnormalities
• Sex chromosome abnormalities
• Mosaicism
• Structural chromosome rearrangements
• Genetic causes of infertility
• Chromosomal causes of recurrent miscarriage

Results help fertility specialists and genetic counselors develop personalized reproductive management plans and assess the likelihood of successful future pregnancies.
