Slight elevation of LD corresponds to which ULN range?

Explanation:
Interpreting how much LDH is elevated relative to the ULN helps gauge the degree of tissue damage. LDH is a ubiquitous cytosolic enzyme released during cell injury, so its level in blood is reported as multiples of the upper limit of normal. A slight elevation means only a modest increase, typically within three times the ULN. Higher elevations—three to five times ULN or more than five times ULN—point to progressively more extensive tissue injury or more significant conditions. Since LDH is non-specific, context from symptoms and other tests is important, but for a mild rise, the appropriate range is up to 3x ULN.
