Streptococcus DNA Detection by Nucleic Acid Amplification Probe
This test checks for genetic material from certain bacteria called *Streptococcus* in your body fluids, often used to diagnose infections caused by these bacteria.
["Helps confirm if a throat, skin, or other infection may be caused by *Streptococcus* bacteria."]

What This Test Measures
The test detects specific DNA sequences unique to *Streptococcus* bacteria. It uses a probe to identify these sequences in a sample, helping confirm the presence of the bacteria without growing them in a lab.
Why It’s Ordered
Your healthcare provider may order this test if you have symptoms like sore throat, skin rashes, or other signs of infection that *Streptococcus* could cause, especially in children or those with recurring infections.
Sample Collection
A swab sample (e.g., from your throat, skin, or other affected area) is collected and sent to the lab. The DNA from any *Streptococcus* bacteria present is extracted and analyzed.
How Results Are Interpreted
Results are qualitative (positive or negative). A positive result means *Streptococcus* DNA was found, suggesting an infection may be present. A negative result means no DNA was detected, but other tests or clinical judgment may still be needed.
Reference range
INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A
Inform your healthcare provider if you are taking blood thinners. No special preparation required.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is particularly useful for diagnosing infections like strep throat, cellulitis, or other *Streptococcus*-related illnesses quickly. It can help guide treatment decisions, such as starting antibiotics if needed, and reduce unnecessary testing or delays in care.
