Widal Test (Slide Method) in Ranchi - Price & Details

PharmEasy Labs does the risk assessment for typhoid and paratyphoid fever through the Widal test (slide method). A person gets typhoid fever when he consumes food or contaminated words by the faeces of an infected person recovering from the disease. You might be exposed to infection a while back but you may still catch a fever. It takes about six to thirty days to catch a fever after the infection. Once you visit the doctor, you will be recommended the widal test (slide method).

There are two ways to conduct this test:

• Slide agglutination test: This is when a test is used for the diagnosis of typhoid and is processed on a slide
• Tube agglutination test: When the test is conducted in a test tube

If we compare the two methods, the slide agglutination test is preferred more and is considered to provide better confirmation of the titres. A couple of blood samples will be needed to perform the test within seven to ten days. You should usually do this test after one week of continuous fever.

If your body is showing signs of typhoid fever, it will become necessary to do a widal test (slide method). Here are the major symptoms of this test:

• High fever with head and body aches
• Red Spots on the body
• Abdominal pain, constipation, and possibly diarrhoea.
• Weakness and a loss of appetite
• Agitation, confusion, and hallucinations

All these are some major concerns and you shouldn't take too much time before going for the widal test (slide method). As we have already said, you should do the test one week after you catch a fever.

No fasting is required to do the test. However, your healthcare provider may advise you to avoid certain medications or foods before the test. So make sure to get in touch with him before the test.

During the Widal Test

An experienced phlebotomist will locate the vein with the help of a vein finder. Then he will collect the blood sample from the patient and let it clot. Once the clot is formed, the sample is centrifuged to separate the serum from the cells. The phlebotomist will keep all the hygienic requirements in mind while doing the whole procedure.
