SCRUB TYPHUS RAPID TEST (IGG/IGM): Symptoms, Test, Results & More
Scrub typhus is a bacterial infection that can cause fever and other flu-like symptoms. It is caused by Orientia tsutsugamushi and is transmitted through the bite of infected chiggers, which are tiny mites commonly found in areas with dense vegetation. In India, scrub typhus can occur in several regions, particularly during and after the monsoon season.
The SCRUB TYPHUS RAPID TEST (IGG/IGM) is a blood test that helps detect antibodies produced by the body in response to scrub typhus infection. It can help healthcare professionals assess whether a person may have a recent or previous exposure to the infection. If you have persistent fever, headache, body ache, or other symptoms suggestive of scrub typhus, your doctor may recommend this test along with clinical evaluation.

Why Is the Scrub Typhus Test Important?
Scrub typhus can initially resemble other common causes of fever, including viral infections, dengue, malaria and other bacterial illnesses. Because the symptoms can overlap, identifying the possible cause of prolonged or unexplained fever can be important for appropriate medical management.
Doctors may consider a SCRUB TYPHUS RAPID TEST (IGG/IGM) when a patient has symptoms such as persistent fever and a possible history of exposure to areas where scrub typhus occurs.
Testing may be particularly relevant for people who have recently travelled to rural or vegetation-rich areas, worked outdoors, or experienced a possible mite bite.
Who Should Consider a SCRUB TYPHUS RAPID TEST (IGG/IGM)?
A healthcare professional may recommend the test if you experience symptoms that could be associated with scrub typhus, especially when the cause of fever is unclear.
Common symptoms can include:
- Persistent or high fever
- Headache
- Muscle and body aches
- Chills
- Weakness or fatigue
- Swollen lymph nodes
- Skin rash in some cases
- Nausea or vomiting
- Reduced appetite
Some people may also develop a small darkened area or scab-like lesion at the site of a chigger bite, known as an eschar. However, its absence does not necessarily rule out scrub typhus.
If fever is persistent, severe, or accompanied by breathing difficulty, confusion, extreme weakness, seizures, or other concerning symptoms, seek medical attention promptly rather than relying solely on a diagnostic test.
How Is the SCRUB TYPHUS RAPID TEST (IGG/IGM) Performed?
The test generally requires a blood sample. A trained healthcare professional collects the required sample using standard procedures.
The sample is then tested for IgM and IgG antibodies associated with scrub typhus. The results are interpreted according to the laboratory’s reference range and testing method.
For many patients, the process is straightforward and requires only a routine blood sample. However, preparation requirements can vary depending on the test and laboratory. It is advisable to follow the instructions provided at the time of booking or sample collection.
Understanding IgM and IgG Results
The two antibody markers provide different information.
IgM antibodies are commonly associated with a recent immune response and may become detectable after the infection has progressed for some time. Therefore, testing very early in the illness may sometimes produce a negative result despite infection.
IgG antibodies can persist longer and may indicate previous exposure or an immune response. A positive IgG result by itself does not necessarily confirm an active infection.
For this reason, the SCRUB TYPHUS RAPID TEST (IGG/IGM) should not be interpreted in isolation. Your doctor may consider your symptoms, duration of fever, travel or exposure history, physical examination, and other laboratory findings.
SCRUB TYPHUS RAPID TEST (IGG/IGM) vs Other Fever Tests
Patients with unexplained fever may undergo several investigations depending on their symptoms and doctor’s assessment. Tests for dengue, malaria, typhoid and other infections may sometimes be considered alongside scrub typhus testing.
The appropriate test depends on the suspected illness and the stage of infection. A doctor can determine which investigations are suitable based on your individual clinical situation.

Frequently Asked Questions
1. What is the SCRUB TYPHUS RAPID TEST (IGG/IGM)?
It is a blood-based antibody test that detects IgM and IgG antibodies associated with scrub typhus infection.
2. What does IgM indicate in scrub typhus?
IgM generally reflects a more recent immune response. However, results should be interpreted according to the timing of symptoms and clinical findings.
3. What does IgG indicate?
IgG may indicate previous exposure or an immune response. A positive IgG result alone does not necessarily confirm an active infection.
4. Is the SCRUB TYPHUS RAPID TEST (IGG/IGM) a blood test?
Yes. The test generally requires a blood sample, which is collected by a trained healthcare professional.
5. Do I need fasting for this test?
Fasting requirements can vary depending on the laboratory and whether other tests are being performed at the same time. Follow the instructions provided when booking your test.
6. When should I take the scrub typhus test?
The appropriate timing depends on the duration of symptoms and your doctor’s assessment. Antibody levels can vary during different stages of infection.
7. Can scrub typhus cause prolonged fever?
Yes. Scrub typhus can cause persistent fever, often accompanied by headache, body aches, fatigue and other symptoms.
8. Can a negative result rule out scrub typhus?
Not necessarily. A negative result may occur if testing is performed early or depending on the sensitivity and characteristics of the test. Your doctor may recommend additional evaluation if symptoms persist.
9. Can IgG remain positive after an old infection?
Yes. IgG antibodies can persist after previous exposure, which is why an IgG-positive result should be interpreted along with symptoms and other findings.
10. Is scrub typhus contagious?
Scrub typhus is generally transmitted through the bite of infected chigger mites rather than through ordinary person-to-person contact.
11. Who should interpret my test results?
A qualified healthcare professional should interpret your report, particularly if you have persistent fever or other significant symptoms.
12. Can I book the SCRUB TYPHUS RAPID TEST (IGG/IGM) online?
Yes. You can check availability and booking options through areyouhealthy.in. Sample collection availability depends on your location and service coverage.
Final Thoughts
The SCRUB TYPHUS RAPID TEST (IGG/IGM) can be a useful diagnostic investigation when scrub typhus is suspected, particularly in people experiencing unexplained or persistent fever with a relevant exposure history. Since IgM and IgG antibodies can appear at different stages, the report should always be considered alongside symptoms, medical history and other investigations.
If you are experiencing persistent fever or symptoms that are getting worse, consult a healthcare professional for appropriate evaluation rather than self-diagnosing based on a test result.
