Whole Exome Sequencing Test - Price, Purpose, Procedure

Whole Exome Sequencing (WES) Test

Sequence all 20,000+ protein-coding genes from a single blood draw to uncover the genetic cause of rare and inherited disorders — with NABL-accredited processing and a report in 32 days.

Quick answer

Whole Exome Sequencing reads the protein-coding part of your DNA — about 1–2% of your genome, but where most known disease-causing mutations occur — from a single blood sample. It's used to diagnose rare and inherited genetic disorders when standard tests haven't found an answer. At Redcliffe Labs it costs ₹19,999 (list price ₹77,000), includes free home sample collection, and the report is ready in 32 days.

What is Whole Exome Sequencing?

Your DNA contains about 20,000 genes, but only their protein-coding regions — called exons — build the proteins your body runs on. Whole Exome Sequencing (WES) sequences just these exons rather than the entire 3-billion-letter genome.

Although the exome makes up only about 1–2% of your DNA, it contains the majority of known disease-causing variations — which is why WES is often the first genetic test ordered for undiagnosed inherited conditions. It is a smaller, faster and more cost-effective test that still captures the region where most disease-causing mutations are found.

WES can also identify carrier status. Carriers have one copy of a gene variant; if both parents carry a variant for the same condition, their children have an increased risk of inheriting the disorder. The test is especially useful if you have a family history of genetic conditions, an unexplained medical condition that may be genetic, or if you are planning a pregnancy.

Purpose of the WES Test

The Whole Exome Sequencing test helps diagnose a range of genetic conditions. It can:

• Identify the cause of unexplained medical conditions that may have a genetic basis.
• Detect whether you carry gene variants linked to a family history of genetic disorders.
• Determine your carrier status for particular genetic conditions.
• Help couples planning a pregnancy understand potential genetic risks to their children.

Who should take the WES Test?

• You or a family member has an undiagnosed condition suspected to be genetic.
• A child has developmental delay, intellectual disability, or unexplained seizures.
• You have a family history of a genetic disorder.
• You and your partner are planning a pregnancy and want carrier screening.
• A doctor has recommended genetic testing after ruling out common causes.

Your doctor will review your medical history, family background and specific concerns to recommend whether WES is the right test for you.

What the WES report indicates

• Identified variants — the report details the variations found in your genes compared with a reference genome, categorised by their potential impact.
• Carrier status — the report interprets these variants against known genetic diseases and indicates whether you are a carrier for any condition.

If you have any questions about your report, consulting a healthcare professional or genetic counselor is highly recommended.

WES vs Whole Genome Sequencing vs Karyotyping

The right genetic test depends on what a clinician suspects. Here is how the three most common options differ.

Preparation

Whole Exome Sequencing requires minimal preparation:

• Discuss with your doctor — share your medical history and concerns so they can explain the benefits and limitations of the test.
• No fasting — the WES test does not require fasting.
• Medication — do not take any over-the-counter medicine without confirming with your doctor.

How it works — 3 steps

• Book online or call 898 898 8787 — pick a home-collection slot, available pan-India, 7 days a week.
• Free at-home blood draw — a trained phlebotomist visits your home; no fasting required; the sample is transported in a temperature-controlled kit.
• Report in 32 days + free consult — your DNA is sequenced and analysed, and results are reviewed with a geneticist over a free doctor consultation.

During collection, the phlebotomist cleans the site, applies a tourniquet and draws the sample with a sterile needle; you may feel a slight pinch, which passes quickly. The sample is then sent to the laboratory for analysis.
