Molecular Diagnostics & PCR Tests in Visakhapatnam
Highly sensitive DNA and RNA based tests that detect infections and genetic markers with precision.
About molecular diagnostics at SMS Diagnostics
Molecular diagnostics detect the genetic material (DNA or RNA) of a virus, bacterium or the patient's own cells. Techniques such as PCR (polymerase chain reaction) and RT-PCR amplify tiny amounts of genetic material, making these tests extremely sensitive and specific. They can often identify infections earlier than antibody tests and can measure the amount of virus in the blood.
SMS Diagnostics, Visakhapatnam assists patients and doctors with molecular test enquiries, from respiratory virus detection to viral load monitoring. Because molecular tests require special sample handling, please contact us before your visit so we can confirm availability, the correct sample type and reporting time.

Frequently asked questions
Tap a question to see the answer.
What is the difference between PCR and an antibody test?
PCR detects the genetic material of the organism itself, showing current infection. An antibody test shows your immune response, which can indicate a current or past infection.
How long do PCR test results take?
Report timing depends on the specific test and how samples are batched. Please contact SMS Diagnostics for the expected turnaround of the test you need.
Is a viral load test the same as a screening test?
No. Screening tests detect whether an infection is present. A viral load test measures how much virus is present and is mainly used to guide and monitor treatment.
Do I need a doctor's prescription for molecular tests?
A prescription is recommended so that the correct test is ordered and the result can be interpreted by your doctor.
