Lab Value Interpretation

2. Abbreviation: Measures intrinsic pathway; used to monitor heparin therapy.
9. Primary antibody providing long-term immune protection; low levels increase infection risk.
12. Iron-rich protein that measures oxygen-carrying capacity; low levels may cause fatigue and shortness of breath.
13. Percentage of red blood cells in blood; often decreases with anemia.
15. Reflects total red blood cells; decreased in anemia related to cancer or treatment.
17. Critical for cardiac rhythm; closely monitored during tumor lysis syndrome.
20. Reflects acid–base balance; low levels may indicate metabolic acidosis.
21. Key lab for bleeding risk; help your blood to clot.
23. Most reliable indicator of renal function; impacts chemotherapy dosing.
24. Indicates clot breakdown; may be elevated in malignancy or thrombosis.
26. Main protein in your blood; made in the liver.
27. Assesses kidney function and hydration status.

1. Supports neuromuscular and cardiac function; low levels may worsen arrhythmias and are common with certain chemotherapies.
3. Abnormal levels may indicate bone metastases or tumor lysis syndrome.
4. Electrolyte involved in cellular energy; elevated levels are common in tumor lysis syndrome.
5. Measures clotting via the extrinsic pathway; used to monitor warfarin.
6. Essential clotting protein; may be decreased in DIC.
7. Blood sugar level; may be elevated with steroids used in cancer treatment.
8. Works with sodium to maintain fluid balance and acid-base status.
10. Primary indicator of immune function and infection risk; often suppressed by chemotherapy.
11. Most important value for determining neutropenic precautions.
14. Marker of tissue hypoxia; elevated levels may indicate sepsis or poor perfusion.
16. Inflammatory marker that rises with infection, tissue injury, or malignancy.
18. Byproduct of cell breakdown; elevated levels increase risk for kidney injury in tumor lysis syndrome.
19. Electrolyte affecting neurologic status; abnormalities may be seen with SIADH.
22. Waste product created from the breakdown of old red blood cells; filtered by the liver.
25. Abbreviation: A standardized value used to assess anticoagulation therapy safety.
