This is a diagnostic test that helps your healthcare provider learn important information about your health. By analyzing a sample collected from your body, the test can detect changes or abnormalities that may indicate an underlying condition, guide treatment decisions, or confirm that a current treatment plan is working as expected.

The Acinetobacter Species Identification by Sequencing test is a molecular diagnostic test that uses genetic sequencing to identify the exact species of Acinetobacter bacteria present in your blood sample. Acinetobacter is a group of bacteria commonly found in the environment and healthcare settings. Some species can cause serious infections, particularly in people who are already ill or have weakened immune systems.

The test is usually performed by a trained healthcare professional in a clinic, hospital, or laboratory setting. It may involve collecting a small sample of blood, urine, or other body material, depending on what your doctor has ordered. You may receive preparation instructions, such as fasting for several hours beforehand, and the collection itself is typically quick, safe, and causes only minimal discomfort.

A healthcare provider will collect a blood sample from a vein in your arm. The sample is then sent to a specialized laboratory where technicians extract the genetic material (DNA) from any bacteria present. Using advanced sequencing technology, the laboratory can identify the specific Acinetobacter species. This method is more precise than traditional culture techniques and can provide results that guide targeted treatment.

Your doctor may recommend this test to help diagnose the cause of symptoms you are experiencing, to screen for a condition before it causes problems, to monitor an illness you already have, or to check how well a treatment is working. In some cases, the test is also part of a routine checkup to keep track of your overall health.

Your doctor may order this test if you have symptoms of a bacterial infection and standard tests have detected Acinetobacter. The test is particularly important because different Acinetobacter species may respond differently to antibiotics. Knowing the exact species helps your doctor choose the most effective treatment, especially in cases of antibiotic-resistant infections.

Your results are compared with a normal reference range to show whether your values are within expected limits. Results that fall within the normal range generally suggest no abnormality, while values that are too high or too low may point to a condition that needs further evaluation. Your healthcare provider will explain what your specific results mean in the context of your symptoms, medical history, and overall health, and will discuss any next steps with you.

A positive result indicates that a specific species of Acinetobacter has been identified in your blood. Your doctor will use this information, along with other clinical findings, to determine the best treatment approach. A negative result means no Acinetobacter DNA was detected, though this does not rule out other types of infection.

Reference range

No Acinetobacter species identifiedN/A

Specimen: serum

No special preparation required. Collect specimen using standard venipuncture procedures. Inform laboratory if patient has received antibiotics prior to collection as this may affect results.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test plays a critical role in managing Acinetobacter infections, which are a significant concern in healthcare settings. Acinetobacter baumannii is the most common disease-causing species and is often resistant to multiple antibiotics. Accurate species identification helps guide antimicrobial therapy and may contribute to infection control measures in hospital settings. The test is particularly valuable for patients with bloodstream infections, pneumonia, or wound infections caused by Acinetobacter, helping to improve outcomes and potentially reduce the spread of antibiotic-resistant strains.

Frequently asked questions

Is this test painful?
The test requires a standard blood draw, which may cause brief discomfort or a minor bruise at the needle site. The procedure typically takes only a few minutes.
How long does it take to get results?
Results are usually available within 2-5 days, as the test requires specialized laboratory processing and genetic sequencing analysis.
Do I need to fast before this test?
No fasting is required for this blood test. You can eat and drink normally before and after the sample collection.
What happens if the test shows antibiotic-resistant Acinetobacter?
If antibiotic-resistant Acinetobacter is detected, your doctor will work with an infection specialist to select alternative antibiotics that may be effective. Additional infection control precautions may also be implemented to prevent spread.
Can this test be done on other specimen types?
While this test description specifies serum (blood), similar sequencing tests can be performed on other samples such as respiratory secretions, wound swabs, urine, or cerebrospinal fluid depending on the suspected infection site.
