Let's Find Out When Fever Is Normalised and When Not ???

Fever is one of the most common health concerns that affects people of all ages. It’s not a disease in itself but a sign that your body is fighting an infection or inflammation.

At AK Diagnostics, we help patients identify the underlying cause of fever through accurate and reliable diagnostic testing — because every fever has a story behind it.

What Is a Fever?

A fever is a temporary rise in body temperature, usually above 98.6°F (37°C), often due to an underlying infection. It is the body’s natural defence mechanism — a way to make it harder for bacteria and viruses to survive.
Mild fevers are generally harmless and may even be beneficial, but a high or prolonged fever can indicate a more serious condition that needs medical attention.


Common Causes of Fever

Fever can be triggered by a wide range of conditions. Some of the most common include:

  • Viral Infections – Common cold, flu, dengue, COVID-19, or viral gastroenteritis.
  • Bacterial Infections – Typhoid, pneumonia, urinary tract infections, or tonsillitis.
  • Parasitic Diseases – Malaria and other mosquito-borne infections.
  • Inflammatory Conditions – Autoimmune disorders or inflammatory diseases.
  • Heat Exhaustion or Sunstroke – Prolonged exposure to high temperatures.
  • Post-Immunisation Fever – Common in children after vaccination.


Knowing the cause is crucial—and that’s where diagnostic testing at AK Diagnostics plays a key role.

Symptoms That May Accompany Fever

Along with elevated body temperature, fever may come with symptoms like:

  • Chills or shivering
  • Sweating and weakness
  • Headache or body pain
  • Dehydration and fatigue
  • Loss of appetite
  • Nausea or vomiting

In severe cases, symptoms like confusion, persistent vomiting, rash, or shortness of breath may signal a medical emergency and should not be ignored.

Why Diagnostic Tests Are Important for Fever

Fever can have multiple causes, and identifying the exact reason is essential for correct treatment. At AK Diagnostics, our team offers a wide range of fever panels and laboratory tests to quickly and accurately pinpoint the cause.

Some of the most commonly recommended tests include:

  • Complete Blood Count (CBC) – Helps detect infection and inflammation.
  • Malaria & Dengue Tests – For mosquito-borne infections.
  • Typhoid (Widal Test or Typhi Dot) – To confirm bacterial infection.
  • Urine & Stool Analysis – To identify systemic or gastrointestinal causes.
  • COVID-19 RT-PCR or Antigen Tests – When viral infection is suspected.

    Our advanced testing methods ensure fast, accurate, and reliable results, helping doctors make better treatment decisions.

    When Should You See a Doctor?

    Seek medical advice if:

    • Fever persists for more than 3 days.
    • Temperature rises above 102°F (38.9°C).
    • There are severe symptoms such as chest pain, rash, or confusion.
    • The fever occurs in infants, the elderly, or people with weak immunity.

      Early diagnosis helps in timely treatment and prevents complications.

      Fever Care Tips

      While waiting for test results or medical consultation:

      • Stay hydrated and drink plenty of fluids.
      • Take rest and avoid overexertion.
      • Use light clothing to prevent overheating.
      • Take medicines only as prescribed by your doctor.
