What is a blood culture test?

This test analyses a sample of blood to detect the presence of fungi or bacteria that may cause infections. Once collected, the blood sample is placed in a sterile container and cultured in a laboratory to allow any microorganisms to grow, which are then identified and analysed.

Purpose of a blood culture test

  • Monitoring Progress: Repeated tests allow healthcare professionals to monitor treatment effectiveness and confirm if the bloodstream is free of infections.
  • Diagnosing Infections: This test helps identify infections in the bloodstream by detecting the specific germs causing symptoms. If a viral infection is suspected, alternative testing may be required.
  • Treatment Planning: Following the growth of germs in the lab, a sensitivity test identifies the most effective antibiotic for the infection.
  • Assessing Infection Severity: Blood cultures can determine whether the infection has spread to the bloodstream, a condition that may lead to sepsis, a potentially life-threatening inflammatory response.
  • Identification: The laboratory grows any bacteria or fungi from the blood sample to pinpoint the exact organism causing the infection.

How is the test conducted?

A healthcare provider will order the test, which may involve taking multiple blood samples from different sites. This procedure is typically performed in a clinic, hospital, or GP surgery and sent to a lab for analysis.

Can the test be performed at home?

Blood culture tests require specialised techniques and equipment. Therefore, they cannot be conducted at home and must be carried out by trained medical personnel.

Cost of a blood culture test

The price varies depending on:

  • Health insurance coverage and any applicable additional fees.
  • The location where the sample is taken.
  • The specific tests conducted alongside the culture.
  • The number of samples required.

For those with private health insurance, checking with your provider to confirm coverage details and potential out-of-pocket costs is advisable.
