Commonly used sepsis tests

Sepsis or septicaemia is a serious, life-threatening general condition of the person. The clinical manifestations of sepsis are quite diverse because it affects many bodies in the body.

Diagnosis of the disease requires multiple sepsis tests, of which blood cultures are the gold standard. A positive response blood transplant test result allows to conclude that the patient is suffering from sepsis. However, the positive rate of blood culture tests is not high and is not agreed between laboratories. Therefore, a negative blood culture test cannot exclude sepsis.

1. Learn about sepsis

Sepsis is a serious disease that threatens the life of the person. This is a system infection caused by the penetration of pathogenic microorganisms into the bloodstream, causing impaired function of various bodies in the body. Pathogenic microorganisms can come from bacterial drives from unman controlled bodies that should spread into the blood or microorganisms when entering the body that attack directly into the bloodstream, multiply and be taken by blood to other bodies in the body. Therefore, it is very easy to fall into the context of multi-agency failure and septic shock, which can eventually die. Manifestations of multi-agencyal ins depleting that may be clinically encountered are:

  • Acute Respiratory Distress Syndrome (ARDS);
  • Acute hepatic impairment;
  • Emergency renal failure;
  • Myocardial necrosis;
  • Hemolysis, visceral hemorrhage;
  • Necrosis of the muscles such as the liver, kidneys, intestines.

Acute respiratory distress

Besides sepsis, an unusual medical condition is often referred to as sepsis. Sepsis is defined when there is evidence of the presence of bacteria in the patient's blood such as a positive blood culture test but no clinical manifestations.

According to data from the U.S. Centers for Disease Control and Prevention, more than 20,000 cases of sepsis over the age of 65 have dementia each year, according to data from the U.S. Centers for Disease Control and Prevention. Sepsis is believed to be the 11th leading cause of death.

Some people considered at risk of sepsis should be noted including those with ineffective immune systems, susceptibility to pathogenic microorganisms, or those with severe bacterial diseases in the agencies. Some cases are listed as follows:

  • Infants, young children;
  • Older people;
  • People with weakened immune systems such as HIV/AIDS patients;
  • Patients with prolonged chronic conditions such as diabetes mellitus, malignant diseases, the use of immunosuppressive drugs, anti-fragmentation drugs continuously for long periods of time;
  • People with acute infectious diseases: Pneumonia patients are about 12% at risk of sepsis, urinary tract infections are 17% at risk of sepsis, while the risk of sepsis of patients with in visceral infections in the abdomen is about 5%;
  • Acute osteomyelitis;
  • Widespread cellulitis;
  • The patient must undergo major surgeries, lying long in one position;
  • People carry many instruments that are invasive to the body such as ine management, urinary sonde, gastric sonde.

2. Sepsis tests

Sepsis is a severe pathology with diverse and endangered clinical manifestations, however the diagnosis of a case of sepsis should be based on subclinical tests. Some of the basic sepsis tests commonly used clinically are:

  • Blood culture test;
  • Total peripheral blood cell analysis;
  • Quant quantity of inflammatory indicators such as the rate at which the blood settles (VS), CRP, procalcitonin;
  • Quantate blood lactate levels;
  • Testing for renal and liver function;
  • The test evaluates renal liver function.

Blood cultures, bacterial cultures

Blood culture test used

In particular, blood culture testing is the gold standard for diagnosis of sepsis. The blood of the person should be taken at the time of high fever or malaria tremor, before antibiotics are used. However, antibiotics are delayed in severe cases. In case the patient has been given antibiotics for treatment and wants to take blood for a blood culture test, the antibiotic should stop using it for at least 24 hours. Blood products taken for testing are intravenous blood, the process of obtaining the disease should ensure absolute ermity to avoid contamination of bacteria from the environment or surrounding items. The amount of blood to be taken for each blood culture test is about 20 to 30 ml. Getting the necessary volume of blood plays a role in increasing the detection rate of pathogenic microorganisms. In addition to blood, a suspected case of sepsis should be taken from primary bacterial infections such as respiratory fluid, pus, urine for testing for bacteria. The results of blood transplantation and implantation of the disease are positive for a pathogen that increases the accuracy of the test. Blood culture tests in addition to helping identify pathogenic microorganisms also support the implementation of antibiotic tests, finding antibiotics that sensitive bacteria should help increase the effectiveness of treatment.
