Rheumatic Fever Diagnosis and Evaluation
How Is Rheumatic Fever Diagnosed in Children?
Diagnosing Rheumatic Fever (Romatizmal Ateş) is a complex clinical “detective” process. There is no single laboratory test, imaging scan, or biopsy that can definitively say a child has the disease. Instead, doctors must look at the “big picture” of a child’s symptoms over time, combined with evidence of a recent immune system battle against bacteria.
Because the disease mimics many other conditions—such as juvenile arthritis, leukemia, or viral infections—the evaluation must be meticulous to avoid both under-diagnosis and unnecessary long-term treatment.
At Liv Hospital, we follow the internationally recognized Revised Jones Criteria. This framework requires evidence of a preceding Group A Streptococcus infection plus a specific combination of “Major” and “Minor” clinical findings. Our goal is to catch the inflammation while it is still “active,” allowing us to intervene before the heart valves are permanently scarred.
Evidence of Preceding Strep Infection
Before applying the Jones Criteria, we must prove the child had a Strep infection roughly 2–4 weeks ago.
Applying the "Major Criteria"
According to the Jones Criteria, a diagnosis requires two major signs, or one major and two minor signs.
Assessing the "Minor Criteria"
Minor signs are supportive clues that indicate a systemic inflammatory state:
Echocardiogram (Heart Ultrasound)
Every child suspected of having Rheumatic Fever must have an Echocardiogram.
Electrocardiogram (ECG/EKG)
An ECG measures the electrical rhythm of the heart.
Inflammatory Markers (ESR and CRP)
Neurological Evaluation (Chorea Assessment)
If a child is clumsy or moving strangely, a pediatric neurologist may perform specific tests.
Differential Diagnosis: Ruling Out "Look-Alikes"
The evaluation must rule out:
Joint Fluid Analysis (Arthrocentesis)
In rare cases where only one joint is swollen (monoarthritis), a small needle may be used to draw fluid from the joint.
Chest X-Ray
If the child has signs of heart failure (shortness of breath or coughing), a chest X-ray is taken.
How Does Liv Hospital Diagnose Rheumatic Fever?
At Liv Hospital, we enhance the Jones Criteria with advanced technology. Our Pediatric Cardiology team uses Speckle Tracking Echocardiography to detect subtle heart muscle changes even before they appear on standard ultrasound.
To ensure accuracy, suspected Rheumatic Fever cases are reviewed by our multidisciplinary Heart-Immune Board, helping create precise diagnoses and treatment plans that protect your child’s heart.

Yes. By the time symptoms appear, the Strep bacteria may be gone. Blood tests like ASO can show evidence of a recent infection.
Because Rheumatic Fever can affect the heart even when symptoms are mainly in the joints. An echocardiogram checks for hidden valve inflammation.
A murmur is the sound of turbulent blood flow. In Rheumatic Fever it may indicate valve inflammation, but some murmurs are harmless.
During the acute phase, they are usually checked every 1–2 weeks to monitor inflammation.
Yes. Sydenham’s chorea is strongly linked to Rheumatic Fever and may confirm the diagnosis even without joint pain or fever.
