Telomere testing considerations

Are telomere length tests validated as a biomarker of aging in humans?
What do we know about the dynamics of telomere length changes in prospective human longitudinal studies?
Are telomere length tests accurate within ∼5% upon multiple biologic replicates from the same individual?
Do tests provide both the average and percentage of the shortest telomeres?
What does average telomere length mean biologically?
