Leaves of Sequoiadendron giganteum. Giant sequoias are the world's largest single trees and largest living thing by volume. Giant sequoias grow to an average height of 50â85 m (164â279 ft) and 6â8 m (20â26 ft) in diameter. Record trees have been measured to be 94.8 m (311 ft) in height.
The laboratory evaluation included tests for both hepatitis B and C. Tests for hepatitis C consisted of an alanine aminotransferase (ALT) test at a cost of $19.60 per test, an anit-HCV antibody screening test (EIA-2) costing $40.20, and a confirmatory recombinant immunoblot assay (RIBA) costing $148.90.
Using this same means of calculation, the average cost effectiveness for intervention B is $100/QALY and the average cost effectiveness for intervention C is $30/QALY.inally, divide the incremental cost by the incremental benefit. In our example, the incremental cost-effectiveness ratio = (Cost Z â Cost X)/ (QALYs Z â QALYs X)= ($1000-$500)/(25 QALYs -20 QALYs) = $500/5 QALYs = $100/QALY.
