What tests need to pass before the EGD?

 

Proper preparation for diagnostic procedures allows to increase their information content and provide a high level of security, both for the patient and the medical worker. Gastroscopy or fibrogastroduodenoscopy (EGD) in this plan not an exception. What are the tests before gastroscopy? As a rule, several studies of blood and urine to identify hidden somatic and infectious diseases. Understanding the importance of such examination and timely treatment to the doctor for consultations allow patients to obtain the most useful results from examination of stomach and duodenum.

Description gastroscopy

Gastroscopy or FGS – is an endoscopic method for detection of diseases of the upper gastrointestinal tract, namely, esophagus, stomach, and initial segments of the duodenum. This method of examination allows the doctor to visually assess the condition of the mucous membrane of bodies and identifying pathological processes in the earliest stages of their development. EGD is the gold standard in the diagnosis of diseases of the stomach and esophagus, first and foremost, peptic ulcer disease, gastritis, and also benign and malignant tumors.

Many patients who are prescribed gastroscopy, wonder why you need to donate blood prior to such a survey? Your doctor is required to tell patients about the required preliminary examination and explain each separate analysis and the possible results.

You need to pass the biological fluid only on certain procedures, able to be informative in each case. It is important to consult with your doctor.

The reasons for the appointment tests before endoscopy the following:

  1. A gastroscopy is a serious invasive procedure, though extremely rarely, leading to the development of any complications. However, it poses a risk for patients with pathology of internal organs. So blood tests and urine tests help to identify various diseases that have not yet manifested clinical complaints, for example, infectious processes.
  2. In connection with the possible risk of damage to the mucosa with the introduction of the endoscope in the patient may start minor bleeding. However, in patients with various disorders of the hemostatic system can develop life-threatening condition.
  3. The patient can be a carrier of serious diseases that are transmitted through blood. This creates the preconditions for infecting medical personnel at the time of the procedure. Therefore, all patients need to explore the plasma for hepatitis b, C and HIV infection.

Arrangement of proper laboratory diagnosis of diseases allows to increase the informative value of diagnostic procedures and greatly improve its information content.

What tests must pass before the EGD?

What tests pass in preparation for EGD? This is a clinical and biochemical study of blood, blood tests for infection and urinalysis.

The minimum set of tests before FGS shall be the attending physician after examination of the patient.

Clinical analysis of blood

All patients before gastroscopy rent or common clinical analysis of blood, allowing to identify diseases of the internal organs. In particular, thanks to such research easily detect hidden inflammation in the body of the patient and to prevent the carrying out endoscopic examination.

The interpretation of possible results:

  • Increasing quantities of white blood cells (leukocytosis) and increased erythrocyte sedimentation rate, evidence of inflammation, and may precede clinical symptoms.
  • The decrease in the number of platelets may be a risk factor for prolonged bleeding during the procedure.
  • The decrease in the number of red blood cells and hemoglobin, ie, the picture of anaemia, may indicate long-term current disease.

In addition to clinical tests of blood it is important to have and biochemical.

Blood biochemistry and detection of infections

Biochemical research could include several dozens of parameters, but should stop at some of them:

  • Determination of fibrinogen concentration. Fibrinogen – protein of blood coagulation system, however, its increase indicates inflammatory processes in the body that helps to identify them even in the absence of patient’s complaints.
  • C-reactive protein. Another indicator of inflammatory changes in internal organs, widely used in clinical practice.
  • Definition of infectious disease such as viral hepatitis b and C, HIV-infektsiija necessary to ensure the safety of health workers during the examination of an infected patient. In this regard, the data analyses should be taken by all patients who undergo invasive medical procedures.

The purpose of the analyses is an integral part of patient preparation for the upcoming gastroscopy. Detection of latent diseases of internal organs can prevent the development of early and late complications of the procedure and increase its efficiency. If patients have not passed the tests, it would be impossible to identify contraindications to EGD and to protect the patient and physician from possible danger.
