Lysine - Quantitative Urine 24 Hr

This test requires a 24-hour urine sample. You will be given a container to collect your urine at home over a 24-hour period, which you will then return to the laboratory for analysis.

High levels of lysine in your urine could indicate a metabolic disorder that impairs your body's ability to metabolize lysine. On the other hand, low levels could suggest a dietary deficiency. Your healthcare provider will interpret your results in the context of your overall health and other test results.

No, this test does not pose any significant risks. It involves the collection of a urine sample, which is a noninvasive procedure.

No special preparation is needed for this test. However, it's crucial to provide your healthcare provider with a complete medical history, including information about your diet, medications, and supplements.

No, this test does not require fasting.

Several factors can affect your test results, including your diet, medications, supplements, and certain health conditions. It's crucial to discuss these factors with your healthcare provider.

Abnormal results don't necessarily mean you have a health problem. If your results are significantly out of range, your healthcare provider will interpret them in the context of your overall health, medical history, and other test results.

Yes, lysine is found in high amounts in animal-based foods. People following a strict vegan or vegetarian diet may be at risk of lysine deficiency if their diet isn't properly balanced.

While stress and lifestyle can influence various biochemical processes in the body, they're not typically associated with changes in urine lysine levels. However, prolonged stress or unhealthy lifestyle habits can impact overall nutrition and may indirectly influence your lysine levels.

Yes, you can continue taking your medications unless otherwise directed by your healthcare provider. However, make sure to inform your healthcare provider about all medications and supplements you're taking as they may influence your test results.

The need for regular testing depends on your personal health situation. Your healthcare provider will guide you on the frequency of testing based on your condition and the necessity to monitor your lysine levels.

Certain metabolic disorders and malnutrition, especially those associated with poor protein intake, can result in abnormal lysine levels. In contrast, certain conditions such as familial hyperlysinemia can result in high levels of lysine in the urine.

Yes, this test can be performed on patients of all ages, including children. It can help evaluate protein nutrition and diagnose metabolic disorders.

Your healthcare provider might order other tests along with this one to get a more comprehensive picture of your health. These tests might include other tests for amino acids, a complete blood count (CBC), or a basic metabolic panel (BMP).

You will be provided with a special container to collect your urine. Start in the morning; after you get up, urinate but do not collect this urine. For the rest of the day and night, collect all your urine in the container provided. The next morning, urinate into the container when you get up, so your first and last samples are taken at the same time.

While lysine is found in higher amounts in animal-based foods, it is also present in plant-based foods like legumes and quinoa. If you're following a vegetarian or vegan diet, it's important to include a variety of plant-based proteins in your meals to ensure you're getting enough lysine.

If you forget to collect some of your urine, it's important to notify the laboratory when you return your sample. They may ask you to start the collection process again to ensure the results are as accurate as possible.

Strenuous exercise may affect the metabolism of amino acids in your body. However, regular moderate exercise should not significantly alter the results of this test. If you have concerns, discuss them with your healthcare provider.

Familial hyperlysinemia is a rare genetic metabolic disorder characterized by an excess of lysine in the blood. This can lead to a variety of symptoms, including developmental delay, seizures, and other neurological problems. This disorder is diagnosed through metabolic screening tests and genetic testing.

Your test results will be sent to your healthcare provider, who will then discuss them with you. In most cases, you can also access your results through a secure online portal.

If you're taking lysine supplements, make sure to inform your healthcare provider, as they may affect the results of this test. Your provider may advise you to stop taking the supplements for a few days before the test.

Yes, lysine plays an important role in many bodily functions, including protein synthesis, tissue repair, and the absorption of certain nutrients. A lysine deficiency can lead to fatigue, nausea, dizziness, loss of appetite, agitation, bloodshot eyes, slow growth, anemia, and reproductive disorders.

This test is highly accurate and reliable for measuring the amount of lysine in the urine. However, the results must be interpreted in the context of your overall health and other laboratory findings.

While the urine sample collection can be done at home, the sample needs to be analyzed in a laboratory. It's important to follow the provided instructions for collecting and storing your urine sample to ensure the most accurate results.
