Test Description
The Lysine Quantitative Plasma test measures the concentration of lysine, an essential amino acid, in the blood.
This test is crucial for assessing the body’s protein nutritional status and can help identify deficiencies or excesses of lysine due to dietary restrictions or metabolic disorders.
Indications of the Lysine Quantitative Plasma Test
This test may be indicated for:
- Evaluating protein nutritional status, especially in individuals with dietary limitations (e.g., vegans, vegetarians).
- Diagnosing potential lysine deficiencies, which can manifest as fatigue, nausea, dizziness, loss of appetite, agitation, and slow growth.
- Monitoring conditions that may lead to abnormal lysine levels, such as metabolic disorders.
Patient Preparation/Instructions
- No specific preparation is required; patients can maintain their normal diet and medications unless directed otherwise by their healthcare provider.
- Inform your doctor if you are taking lysine supplements, as they can influence test results.
Typical Reference Values
Normal lysine levels typically range from 150 to 350 µmol/L, though values may vary slightly between laboratories. Low levels can indicate protein deficiency or malnutrition, while high levels may suggest excessive protein intake or certain metabolic disorders.
Turnaround Time
Results for the Lysine Quantitative Plasma test usually take about 5 to 7 days to process.
