I want to find all instances of lipid tests conducted in the i2b2 database, with a specificity scale of 0 and accuracy scale of 100, and with the panel name "Lipid Tests" and the timing set to "ANY". The query will look for this information under the "Lab Tests" category in the "Chemistry" section, specifically under the "Lipid Tests" subsection.
