One may have typhoid fever if one experiences symptoms like a high fever, exhaustion, diarrhea, constipation, stomach pain, rose spot rashes, dry cough, and headache. For the detection of typhoid fever, doctors recommend the typhoid test. Typhoid fever is caused by Salmonella enterica serotype Typhi bacteria. The infection is caused by consuming contaminated food and water. The typhoid test is used to detect typhoid-causing bacteria in the person's blood using a biochemical agglutination test.

How Does the Typhoid Test Work?

The blood agglutination test is used in the typhoid test procedure to diagnose typhoid fever. Patients with enteric fever will have homologous antibodies in their serum. Typhoid test procedures are classified into two types: slide method and tube method. Agglutination will occur if the serum interacts with the antigen. The typhoid test is a quick diagnostic method with results available on the same day. There are two main types of typhoid tests:

Widal Test

The Widal Test uses antigen-antibody interactions to identify antibodies in the blood of typhoid patients. Pathologists combine serum with a dead bacterial solution of Salmonella containing certain antigens. When antigens are inserted into blood with antibodies in this test, the antigens adhere, and blood aggregates. The test is negative if clumping does not occur. It is time-consuming and may increase the probability of false positives. It can also produce false negatives in those who have recently been infected. That’s why it is important to have this test at a reputable laboratory.

Typhidot Test

The Typhidot Test is commonly used by doctors and healthcare professionals to diagnose typhoid. They believe it is a simple, quick, and promising method for early diagnosis of this health problem. Furthermore, it is suitable for people of all ages. There are no special precautions or pre-testing procedures. However, remember to tell your doctor about any medicines or health supplements you use on a daily basis. You may be advised to discontinue taking the medication several days before the test. Furthermore, inform the doctor and the laboratory technician whether one has any underlying medical conditions. In addition, there is no need for fasting before a Typhidot test.

Purpose of Typhoid Test

The typhoid test is used to diagnose typhoid fever. If a person shows signs of typhoid fever, a doctor may want to examine their typhoid test results. The following are major typhoid fever symptoms to be aware of:

  • Fever
  • Tiredness
  • Diarrhea
  • Dry cough
  • Constipation
  • Pain in the abdomen
  • Rashes on the skin
  • Headache

Because the symptoms of this infection are similar to those associated with other common gastrointestinal disorders, it can sometimes go unnoticed for weeks. However, if any of these symptoms appear, you should see a doctor right once. It is simple to check the typhoid test cost online.

Understanding Typhoid Test Normal Range

The typhoid test lab report includes both quantitative and qualitative clinical analyses of the disease. A typhoid test result within the normal range or a normal level indicates that the individual does not have typhoid fever. A positive typhoid test result, on the other hand, may suggest typhoid disease. However, because the normal range for the typhoid test may differ from one diagnostic lab to another, as well as depending on individual health factors, it is always recommended that one consults a doctor with their typhoid test report. They will be able to understand the normal levels better and recommend a course of action.

It is now quite simple to check the pricing of the typhoid test and book it online. As the typhoid test is used to diagnose a disease that can have serious consequences if left untreated, it is essential to get screened for it as soon as possible. Furthermore, with features like at-home samples taken and online access to the typhoid test report and results, there is no reason to delay.

Typhoid Test Price

A typhoid test is a simple and reasonably priced test that is commonly used in developing countries where typhoid is common. The price of a widal or typhoid test varies according to location, lab center, and other factors. Find the nearest typhoid test lab, make a sample collection appointment, and get your test results the same day. The most ideal recommendation is to schedule the typhoid test at home to make it more comfortable for you.
