PremiumPut several panels on one sheet
This sheet is one panel. The Premium study sheet builder combines any of the 15 panels into a single printable sheet - a whole exam's worth of ranges and critical values on one page instead of 15 separate printouts. Free builds 1 panel at a time, and every panel page stays free to read and print on its own.
Frequently asked questions
What tests are in a Inflammatory & Other Chemistry?
The Inflammatory & Other Chemistry on this page lists 10 tests: Amylase, C-Reactive Protein (CRP), Erythrocyte Sedimentation Rate (ESR), Folate (Folic Acid), Lactate (Lactic Acid), Lipase, Osmolality, Serum, Procalcitonin, Vitamin B12 (Cobalamin), Vitamin D, 25-Hydroxy. Each is shown with its conventional and SI teaching reference range.
What does the Inflammatory & Other Chemistry check for?
CRP, ESR, procalcitonin, lactate, pancreatic enzymes, osmolality, and key vitamins. These are educational teaching values - ranges vary by laboratory and method, and are not for clinical decisions.
Which Inflammatory & Other Chemistry values are critical?
2 of the 10 tests in this Inflammatory & Other Chemistry carry a taught threshold: Lactate (Lactic Acid) (> 4 mmol/L signals significant hypoperfusion / sepsis); Osmolality, Serum (< 265 or > 320 mOsm/kg). These are teaching thresholds, not clinical cutoffs - always use the values your laboratory reports.
