GLOSSARY

Biochemical Assessment uses relevant laboratory measures within a broader clinical and nutritional evaluation.

Laboratory markers provide information within a clinical context rather than a complete nutrition diagnosis. Albumin and prealbumin are affected by inflammation, fluid balance, organ function and other processes, so they should not be interpreted as direct isolated measures of protein intake or muscle mass. A reference interval is not automatically the optimal target for an athlete. Combine relevant tests with intake, physical findings, symptoms and trends, and consider the method and timing before attributing a result to diet alone.

Fasting glucose, glycated hemoglobin, an oral glucose tolerance test and fasting insulin examine different aspects of glucose regulation. Results can be influenced by illness, preparation, medication and other clinical factors. HOMA estimates are model-based surrogate indices and do not directly measure whole-body insulin sensitivity or diagnose an individual in isolation. Interpret units, laboratory methods and the relevant population. Exercise-related changes should be discussed in context rather than labeled as disease or excellent metabolic health from one isolated reading.

A lipid profile needs the measured components, units, sampling conditions and clinical purpose to be clear. LDL, HDL, total cholesterol and triglycerides describe different quantities, while non-HDL cholesterol summarizes cholesterol carried outside HDL. A fasting sample may be requested for particular reasons but is not required for every lipid assessment. Evaluate trends and cardiovascular risk rather than treating one favorable component as permission to ignore an unfavorable one. Athletic status does not make an abnormal result automatically harmless.

Clinical nutrition translates assessment into an individualized intervention and evaluates the response. A disease name alone cannot define the prescription: disease stage, medication, symptoms, laboratory findings, intake and functional goals matter. Screening identifies possible risk, whereas a full assessment supports a nutrition diagnosis and care plan. A sports context adds training demands but does not remove clinical requirements. Coordinate care when medical and performance objectives interact instead of applying a standard athlete menu to every patient.

Nutrition screening identifies people who may need fuller assessment; it does not establish every cause or prescribe treatment by itself. Use a suitable validated tool in the population for which it is intended, then follow a positive result with appropriate evaluation. Include recent intake, unintentional weight change, symptoms and clinical context. Repeat assessment when circumstances change. A negative screen is not a reason to ignore a new concerning symptom or a clear deterioration in the athlete's function.

Nutrition follow-up compares intended goals with actual intake, symptoms, function, relevant measurements and the person's experience. Specify the time frame and what would justify adjustment, continuation or referral. A treatment response can be beneficial, absent or adverse, and adherence alone does not prove effectiveness. Retain enough documentation to understand what changed. For an athlete, consider health and training quality alongside body mass or laboratory results so that apparent progress in one measure does not hide deterioration elsewhere.
