Hello Bahrul!

Thank you for asking HealthReplies.com.

The diagnosis or determination of the type of disease is a conclusion that involves a complete examination process, starting from the interview (history taking), physical examination (seeing, feeling, listening, and tapping), and then additional examinations such as radiological examination, laboratory examination, or microscopic examination . Therefore, determining the type of disease is not only based on laboratory results, but a combination of some of these information and then concluded based on the knowledge and experience of the treating doctor.

The things you mentioned often happen. Some possibilities that can occur when a patient feels certain symptoms, but are not detected by laboratory tests are:

The patient experiences a certain symptom, but the symptom does not yet meet the requirements for the establishment of an illness. For example, symptoms such as coughing, nausea, vomiting, can occur under normal conditions, but the body is not being infected with certain germs, so when laboratory tests are carried out, the results are within normal limits. Laboratory tests examined do not check the type of illness. There are many types of laboratory examinations with different functions and many different types of diseases. If a patient has disease A but what is examined is examination for disease B, then the results will be negative. Therefore it is better to do an examination on the advice of a doctor, because the doctor will ask for a supporting examination in accordance with the patient's condition at the time (complaints and physical examinations carried out). Checks are carried out at inappropriate times, too soon or too late. Certain laboratory tests are only sensitive to checking certain things at certain times. Certain symptoms can occur before they can be detected on laboratory tests, while other symptoms can occur after laboratory tests have returned to normal. Therefore, it takes all the components (symptoms, physical examination, additional examination, and doctor's consideration) to determine an illness, and providing appropriate treatment. If you feel unsatisfied, do not hesitate to consult your doctor about your symptoms.

Hopefully can help.
