What This Test Measures
The test analyzes bacterial DNA or metabolites from a swab of your skin to detect and quantify specific bacterial species. It may also assess overall bacterial diversity and potential markers of skin health or imbalance.
How the Test Works
A sterile swab is used to collect a sample from your skin. The sample is then processed to identify and measure bacterial presence, often using advanced genetic or biochemical methods to detect and quantify different bacterial types.
When You Might Need This Test
This test may be recommended if you have persistent skin issues like infections, rashes, or conditions such as acne, eczema, or psoriasis. It could also be used in research or specialized medical settings to study skin microbiome health.
Sample Collection and Preparation
You will likely have a simple swab applied to your skin, usually in a clean area like the forearm or upper arm. The process is quick and painless, and no special preparation is needed before the test.
Reference range
Negative (No bacilliform bacteria observed)N/A
No fasting required. Skin lesion or affected area should be cleaned prior to specimen collection. Avoid application of topical antibiotics, creams, or ointments for 24-48 hours prior to collection if clinically feasible. Inform laboratory of any recent antibiotic therapy.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
