Preimplantation Genetic Testing, commonly known as PGT testing, is an advanced technique used in fertility care.
It allows doctors to examine embryos for genetic and chromosomal abnormalities before pregnancy.
PGT testing is performed during IVF treatment in Lahore and helps improve pregnancy outcomes.

Understanding which conditions can be detected through PGT testing helps couples make informed decisions about their fertility journey.

What Is PGT Testing?

PGT testing analyzes a small number of cells taken from an embryo created through IVF.
These cells are tested in a laboratory to check for genetic or chromosomal problems.

The goal is to identify embryos with the best chance of leading to a healthy pregnancy.

Chromosomal Abnormalities Detected by PGT

One of the main purposes of PGT testing is to detect chromosomal abnormalities.

These include:

• Extra chromosomes

• Missing chromosomes

• Uneven chromosome numbers

Such abnormalities can prevent implantation or lead to miscarriage.
PGT helps identify embryos with normal chromosome numbers.

Conditions Related to Chromosome Number

PGT testing can detect conditions caused by abnormal chromosome numbers, such as:

• Down syndrome

• Turner syndrome

• Klinefelter syndrome

By identifying these issues early, doctors can reduce the risk of genetic conditions.

Single-Gene Genetic Disorders

PGT testing can detect inherited genetic disorders caused by single gene mutations.

Examples include:

• Thalassemia

• Cystic fibrosis

• Sickle cell disease

• Muscular dystrophy

This type of testing is especially useful when one or both parents are known carriers.

Structural Chromosomal Abnormalities

Some individuals carry structural chromosome changes.

These may include translocations or inversions.
While carriers may appear healthy, these changes can affect embryos.

PGT testing can identify embryos with balanced or normal chromosome structure.

Conditions Linked to Recurrent Pregnancy Loss

Repeated miscarriages are often linked to chromosomal abnormalities.

PGT testing helps detect embryos that may not develop properly.
This reduces the risk of miscarriage and improves implantation success.

Male Factor Genetic Conditions

Certain genetic conditions linked to male infertility can be detected.

These may affect sperm development or embryo health.
PGT testing supports better treatment planning in such cases.

Who Benefits Most from PGT Testing?

PGT testing may be recommended for:

• Couples with known genetic disorders

• Recurrent pregnancy loss

• Advanced maternal age

• Multiple failed IVF cycles

• Severe male infertility

A fertility specialist evaluates suitability carefully.

Limitations of PGT Testing

PGT testing does not detect all possible conditions.

It focuses on specific genetic and chromosomal issues.
Some rare or non-genetic conditions may not be identified.

Doctors explain the benefits and limitations before testing.

Ethical and Counseling Support

PGT testing in Lahore involves important decisions.

Genetic counseling is provided to help couples understand results.
Emotional and ethical considerations are respected.

This ensures informed and confident decision-making.

Final Thoughts

PGT testing can detect a wide range of genetic and chromosomal conditions.
It plays a key role in improving IVF success and reducing genetic risks.

When used appropriately, PGT testing offers clarity and reassurance.
A fertility specialist guides patients through every step of the process.
