Genetic analysis of DNA using a probe for a specific sequence (e.g., single nucleotide polymorphism or mutation detection)
This test checks for specific DNA sequences in your blood sample, often used to identify genetic variations or mutations linked to certain conditions.
["Helps identify inherited or acquired genetic differences that may influence health risks or treatment options."]

What This Test Measures
The test detects a particular DNA segment (probe) that may be associated with a genetic trait, mutation, or susceptibility to disease. The probe binds to matching DNA sequences in your blood sample, allowing for precise identification.
How the Test Works
Your blood sample is analyzed to identify the presence or absence of the targeted DNA sequence. The method may involve techniques like polymerase chain reaction (PCR) or DNA sequencing to amplify and detect the probe.
Common Uses
This test may be used for genetic screening, diagnosing inherited disorders, assessing risk for certain diseases, or confirming genetic counseling results.
Sample Collection
A blood sample is typically collected by a healthcare professional. The DNA extracted from this sample is then tested for the presence of the specific genetic sequence.
Reference range
Negative for Candida glabrata DNA. Reference range applies to asymptomatic individuals without signs of urinary tract infection or colonization.N/A
No special patient preparation is required. Patient should follow standard midstream clean-catch urine collection instructions. Prior to collection, patient should cleanse the periurethral area with antiseptic wipes. First morning void is preferred when possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Results can inform healthcare providers about genetic predispositions, guide personalized treatment plans, or confirm diagnoses related to genetic conditions. Early detection may allow for proactive management of health risks.
