Salivary Albumin (Mass Concentration)
This test measures the amount of albumin protein found in your saliva. Albumin is a key protein that helps maintain fluid balance in your body.
["Salivary albumin can reflect overall protein health and may be checked for research or specific clinical studies."]

Why Is This Test Done?
Salivary albumin testing may be part of a research study investigating protein metabolism, oral health, or systemic conditions. It can also help assess kidney function indirectly, as albumin is filtered by the kidneys.
What Does the Result Mean?
Salivary albumin levels can vary based on hydration status, oral health, and certain medical conditions. Lower levels might suggest kidney issues or protein loss, while higher levels could indicate dehydration or inflammation.
How Is the Sample Collected?
A small sample of saliva is collected using a swab or dropper. You may be asked to spit into a container or use a saliva collection device provided by your healthcare team.
What Are Common Uses?
This test is often used in specialized studies or research rather than routine clinical care. It may help monitor protein status in conditions like kidney disease or certain metabolic disorders.
Reference range
INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A
Inform your healthcare provider if you are taking blood thinners. No special preparation required.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical significance: Salivary albumin can serve as a non-invasive biomarker for assessing protein loss or kidney function, though it is not a standard diagnostic tool. It may be used in research settings to study protein metabolism or oral health.
