Overview
18S rRNA sequencing is a molecular diagnostic technique used to identify and classify eukaryotic organisms, such as parasites and fungi, by analyzing the 18S ribosomal RNA gene. This gene is highly conserved across eukaryotes, making it ideal for phylogenetic studies and infection diagnosis. The test involves isolating DNA from a patient sample, amplifying the 18S rRNA gene using PCR, and sequencing it to determine the genetic makeup of the infectious agent. Unlike traditional culture methods, 18S rRNA sequencing can detect even small amounts of genetic material, allowing for rapid and accurate diagnosis. This is crucial for infections that are difficult to culture or identify microscopically. The test is particularly useful for diagnosing parasitic infections like malaria, toxoplasmosis, and fungal infections such as candidiasis or aspergillosis. By providing precise identification, it guides appropriate treatment, reduces diagnostic delays, and improves patient outcomes. DNA Labs India offers this test at an affordable cost of INR 5000 with free home sample collection across India, ensuring accessibility and convenience for patients.

The purpose of 18S rRNA sequencing is to accurately diagnose infections caused by eukaryotic pathogens, including parasites and fungi, by genetic identification. It helps in determining the specific organism responsible for symptoms, guiding targeted therapy, and monitoring treatment efficacy.

Frequently asked questions
What is 18S rRNA sequencing?
It is a molecular test that sequences the 18S ribosomal RNA gene to identify eukaryotic pathogens like parasites and fungi.
How is the test performed?
DNA is extracted from a sample, the 18S rRNA gene is amplified via PCR, and then sequenced to determine the organism's genetic makeup.
What infections can it detect?
It can detect infections caused by parasites (e.g., malaria, toxoplasmosis) and fungi (e.g., candidiasis, aspergillosis).
Is fasting required before the test?
No, fasting is not required for 18S rRNA sequencing.
What is the cost of the test?
The test costs INR 5000 at DNA Labs India, with free home sample collection.
How long does it take to get results?
Results are typically available within 2 weeks.
Is home sample collection available?
Yes, DNA Labs India offers free home sample collection across India for this test.
What are the symptoms that indicate this test?
Symptoms include fever, chills, nausea, diarrhea, abdominal pain, fatigue, weight loss, skin rash, and breathing difficulties.
How accurate is 18S rRNA sequencing?
It is highly accurate for identifying eukaryotic pathogens, with sequence accuracy often exceeding 99%.
Can this test replace traditional culture methods?
It complements culture methods by detecting pathogens that are difficult to culture, but may not replace all traditional diagnostics.
What should I do if my test is positive?
Consult an infectious disease specialist for appropriate treatment and management.
Is the test covered by insurance?
Coverage depends on your insurance policy; check with your provider for details.
