A significant bronchodilator response indicates that lung function improves measurably after inhaling a medication that relaxes airway muscles. It is assessed during spirometry and helps differentiate asthma from chronic obstructive pulmonary disease and guide treatment decisions.
Lung-RADS Category 3 indicates a pulmonary nodule that is likely benign but requires continued monitoring. It typically necessitates a follow-up CT scan to ensure the nodule remains stable in size.
An invalid pregnancy test result occurs when the test fails to function correctly, typically indicated by the absence of a control line. This outcome suggests the test cannot be trusted to detect human chorionic gonadotropin (hCG) levels accurately. Users are advised to repeat the test with a new kit to ensure reliability.
A low rectal sensation threshold in balloon distention refers to a state of visceral hypersensitivity where an individual perceives the presence of stool or gas at lower volumes than normal. This is typically measured using an anorectal manometry balloon to determine the minimum pressure or volume required to trigger a sensory response.
Reactive cellular changes (RCC) are a common, non‑cancerous finding on a Pap smear that reflect a temporary response of cervical cells to irritation or infection. The result usually indicates a benign process and guides follow‑up rather than immediate treatment.
MRI Conditional is a safety classification used for medical devices and implants that indicates they can be scanned under magnetic resonance imaging (MRI) provided specific conditions are met. The label informs clinicians and patients about the required scanner settings, positioning, and other precautions to avoid adverse events.
TAC stands for Total Active Cannabinoids, a measurement found on cannabis product labels that indicates the combined percentage of all active cannabinoids (such as THC, CBD, CBG, CBN, THCV, and others) present in the product, rather than just THC or CBD alone.
Walking asymmetry describes measurable differences between the left and right sides of a person’s gait. It can result from neurological, musculoskeletal, or biomechanical factors and is used by clinicians to diagnose and monitor various health conditions.

Mixed flora in a urine culture means that more than one type of bacteria was grown from the specimen. It is often associated with sample contamination but can also reflect normal urinary tract flora or a polymicrobial infection, depending on the clinical context.
