Genomic DNA from plasma or serum, extracted and quantified for qualitative or semi-quantitative analysis using a probe-based method

What This Test Measures

The test analyzes DNA extracted from your blood sample, which includes genetic material from your cells. This DNA is then examined using a probe—a small piece of DNA or RNA designed to bind specifically to certain sequences. The probe helps determine the quantity or presence of particular genetic sequences.

Why It’s Done

Blood-based DNA testing can serve multiple purposes, including research studies, genetic screening, or detecting specific genetic markers. For example, it may be used to investigate hereditary conditions, monitor genetic research projects, or assess cellular health in certain clinical scenarios.

Sample Collection and Preparation

Your blood sample will be drawn from a vein, typically in a clinic or lab. The blood is then processed to separate plasma or serum, where DNA is extracted. This DNA is purified and prepared for analysis using the probe technique.

What to Expect Before or After the Test

No special preparation is usually needed beyond standard blood draw instructions (e.g., fasting may be avoided). After testing, results may take several days to weeks, depending on the lab’s workflow. Follow-up instructions will be provided if needed.
