Determining Normal Range for Free Light Chains in Serum Among Twins Summary The objective of this study is to recruit healthy adult identical and fraternal twins for the collection of one teaspoon of blood to be sent to the Clinical Lab at San Francisco General Hospital. The serum will be tested to determine the reference range for free light chains.
View Full Description Full Description Serum free light chains are used to assist in the diagnosis of multiple myeloma . The test measures kappa (K) and lambda (L) chains, and the calculation of the ratio of kappa to lambda (K/L). Previous studies have shown that the K/L ratio does not change over time (1 year). The hypothesis of this study is that healthy twins will have a K/L ratio that are close to each other in value, suggesting that this ratio is genetically linked.
View Eligibility Criteria Eligibility Criteria Inclusion Criteria: Healthy subjects 18-80 years. Must be an identical or fraternal twin (both must be recruited) Exclusion Criteria: Symptoms suggestive of multiple myeloma (e.g., renal insufficiency, anemia, bone pain) -
