Overview of the Rotavirus in Stool by PCR Test
The Rotavirus in Stool by PCR test detects Rotavirus A genetic material directly within a stool sample, supporting diagnosis of active rotavirus gastroenteritis.
The test assesses 1 specialist virology biomarker: Rotavirus A.
Rotavirus is a highly contagious virus that causes acute gastroenteritis.
It is particularly associated with vomiting and watery diarrhoea in infants and young children, although adolescents and adults can also become infected.
Transmission occurs mainly through the faecal-oral route.
The virus can spread easily between household members and within nurseries, schools and healthcare environments.
PCR testing detects viral nucleic acid directly.
This provides more direct evidence of infection than antibody testing.
The assay can identify Rotavirus A even when the amount of virus in the sample is relatively small.
A positive PCR result supports current or recent gastrointestinal infection.
However, molecular testing can occasionally remain positive after symptoms have started to improve because viral genetic material may continue to be shed.
The most important immediate risk from rotavirus is dehydration, particularly in babies, young children, older adults and vulnerable patients.
The test does not assess the degree of dehydration or severity of illness.
A negative result means Rotavirus A was not detected above the assay threshold.
It does not exclude other viral, bacterial or parasitic causes of gastroenteritis.
Where broader infectious diarrhoea is being investigated, a Gastrointestinal Panel can assess multiple pathogens simultaneously.
What Does the Rotavirus in Stool by PCR Test Check?
The test detects Rotavirus A genetic material in a stool specimen. This test measures 1 specialist biomarker.
Rotavirus A
Detects Rotavirus A genetic material in stool using PCR, supporting diagnosis of active or recent rotavirus gastroenteritis.
Who May Benefit From the Rotavirus in Stool by PCR Test?
Rotavirus PCR can be useful where acute infectious gastroenteritis is suspected.
Children with acute watery diarrhoea and vomiting - Rotavirus is an important cause of childhood gastroenteritis.
Adults with significant gastroenteritis following household exposure - Adults can also become infected.
People with symptoms after contact with a confirmed Rotavirus case - Household and institutional transmission can occur rapidly.
People with persistent gastroenteritis requiring pathogen identification - PCR can determine whether Rotavirus A is present.
People with immune suppression and significant diarrhoeal illness - Identifying the infectious cause can be particularly useful.
People requiring investigation during a possible gastroenteritis outbreak - Molecular testing can help identify a specific pathogen.
People with negative bacterial stool tests but continuing acute symptoms - Viral testing can provide additional information.
How to Prepare
A suitable stool specimen is required.
The test does not require a blood draw and the sample can be collected privately using the supplied stool collection materials.
Symptoms and Reasons to Consider the Rotavirus in Stool by PCR Test
Rotavirus usually causes an acute gastrointestinal illness.
Watery diarrhoea - Frequent loose stools are a characteristic symptom.
Vomiting - Vomiting often occurs early in the infection.
Fever - Mild or moderate fever can accompany gastroenteritis.
Abdominal cramps - Intestinal infection can cause discomfort and cramping.
Reduced appetite - Acute gastrointestinal illness commonly reduces food intake.
Signs of dehydration - Reduced urine, dry mouth, lethargy or dizziness can occur after substantial fluid loss.
Recent contact with somebody with gastroenteritis - Rotavirus can spread easily through close contact.
Young children can become dehydrated rapidly.
Marked lethargy, inability to keep fluids down, very little urine, severe abdominal pain, blood in stool or signs of significant dehydration require prompt medical assessment.

Receive your results securely
Your authorised result is delivered securely and can be considered alongside symptoms and broader gastrointestinal testing where required.
When Will I Receive My Results?
The current specialist laboratory turnaround for Rotavirus in Stool by PCR is approximately 1 day after laboratory receipt.
The stool specimen undergoes nucleic-acid extraction, molecular amplification, laboratory quality control and result authorisation.
Understanding Your Results
A positive result means Rotavirus A genetic material has been detected in the stool specimen.
This supports current or recent Rotavirus infection when compatible gastrointestinal symptoms are present.
PCR positivity does not measure the severity of illness.
Viral material can also remain detectable while gastrointestinal symptoms are improving.
A negative result means Rotavirus A was not detected above the assay threshold.
This does not exclude other causes of gastroenteritis.
Norovirus, Adenovirus, Sapovirus, bacterial pathogens and parasites can produce similar symptoms.
A broader multiplex gastrointestinal PCR panel may therefore be appropriate when the cause remains uncertain.
Why Book With London Blood Tests?
London Blood Tests provides private Rotavirus PCR testing for direct investigation of acute viral gastroenteritis.
Detects Rotavirus A directly - PCR identifies viral genetic material in stool.
Useful in acute diarrhoeal illness - The test can help establish whether Rotavirus is responsible.
Molecular rather than antibody testing - The assay investigates the organism directly.
