Understanding Your Laboratory Test: Sample Collection and What the Results Mean

This laboratory test gives your healthcare provider important information about your health by measuring substances in your body. It can be used to screen for illness, confirm or rule out a diagnosis, monitor an ongoing condition, or check how well a treatment is working. Your provider will explain why this test was ordered for you and what specific findings they are looking for.

The adenoma histology test is a laboratory examination that analyzes tissue samples under a microscope. Adenomas are benign (non-cancerous) tumors that can develop in various organs, including the colon, thyroid, pituitary gland, and adrenal glands. This test helps pathologists determine whether a growth is an adenoma or if it has features that require further investigation.

The way your sample is collected depends on the type of test your provider ordered. Most often, a trained technician draws a small amount of blood from a vein in your arm with a thin needle, a process that usually takes only a few minutes. Some tests instead require a urine sample, a throat or nasal swab, or a saliva sample. You may receive special instructions, such as fasting beforehand, so follow them carefully and tell the staff about any medications you take.

Unlike blood tests that use serum, adenoma histology requires a tissue sample. This tissue is obtained through procedures such as colonoscopy with polyp removal (polypectomy), surgical biopsy, or fine-needle aspiration. The collected tissue is then preserved and sent to a laboratory where a pathologist examines it under a microscope.

Your results are compared with established reference ranges to show whether your values fall within the expected range. A result within the normal range generally suggests no problem in the area being tested, while a value that is too high or too low may point to a condition that needs further evaluation. Keep in mind that factors such as age, medications, and recent meals can affect results, and a single abnormal value does not automatically mean you are ill. Always review your results with your healthcare provider, who can interpret them in the context of your symptoms and medical history and decide whether additional testing or treatment is needed.

The histology results provide important information about the tissue, including: whether the growth is benign (adenoma) or malignant (cancer), the specific type of adenoma, cell characteristics and growth patterns, and whether complete removal was achieved. Your doctor will explain these findings and what they mean for your specific situation.
