DNA Ploidy Analysis (Specimen Fluid)
This test measures the number of DNA copies in cells from a body fluid sample, often used to assess whether cells are growing abnormally (e.g., in tumors).

Why Might This Test Be Ordered?
Your healthcare provider may recommend this test if you have symptoms like unexplained lumps, persistent pain, or other signs of possible cancer. It’s also used in certain types of biopsies or liquid biopsies to monitor treatment response or detect early signs of cancer in fluids like blood or urine.
How Is the Sample Collected?
A small sample of body fluid (such as blood, urine, or other bodily fluids) is collected and sent to a lab. The lab analyzes the DNA content in the cells within that sample to determine if they appear normal or abnormal.
What Does the Test Result Mean?
Results are typically described as diploid (normal) or aneuploid (abnormal, often with extra or missing chromosomes). Aneuploidy is often linked to cancerous growths, but not all aneuploid results indicate cancer. Your doctor will discuss the results in the context of your symptoms and medical history.
What Are the Possible Risks?
There are generally no risks associated with collecting a small fluid sample for this test. However, if the sample is taken from a vein (e.g., blood draw), there may be a slight risk of bruising, pain, or infection at the site.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
DNA ploidy testing is primarily used in oncology to identify abnormal cell division patterns that may suggest malignancy. It can help guide treatment decisions, monitor disease progression, or assess the effectiveness of therapies. While often performed on solid tissue biopsies, it can also be done on fluid samples (e.g., blood or urine) in certain clinical scenarios, such as liquid biopsies or cytology samples.
