D-dimer is a small protein fragment found in blood when a blood clot is being broken down. It is measured with a laboratory blood test. Clinicians commonly use D-dimer when evaluating possible blood clots in veins or lungs. In cancer care, it may be considered because cancer and its treatments can increase clotting risk.

Ferritin is a protein that stores iron inside the body’s cells. A Ferritin blood test estimates how much iron your body has in reserve. It is commonly used in oncology and general medicine when evaluating anemia, inflammation, and iron overload.

ESR is short for erythrocyte sedimentation rate. It is a blood test that reflects how much inflammation is present somewhere in the body. ESR is commonly used in general medicine, rheumatology, infectious disease, and oncology. In cancer care, it is used as supportive information rather than a stand-alone cancer test.

CRP stands for C-reactive protein. It is a protein made mainly by the liver that rises in the blood when there is inflammation in the body. CRP is most commonly measured with a blood test. In oncology, it is often used to help evaluate infection, inflammation, and overall illness burden during cancer care.

LDH stands for lactate dehydrogenase. It is an enzyme found in many tissues, including blood cells, liver, heart, muscles, and some tumors. In oncology, LDH is most commonly discussed as a blood test result that can reflect tissue damage or rapid cell turnover. It is used as a supportive lab marker alongside imaging, pathology, and other laboratory tests.

A Coagulation panel is a group of blood tests that assess how well blood clots. It helps clinicians understand bleeding risk and clotting tendency. It is commonly used in cancer care before procedures and during certain treatments. It can also help evaluate symptoms like unusual bruising, bleeding, or suspected blood clots.

A Tumor markers panel is a group of laboratory tests that measure specific substances linked to certain cancers. These substances (called “tumor markers”) are usually measured in blood, and sometimes in urine or other body fluids. Clinicians use Tumor markers panel results alongside imaging, physical exams, and biopsy findings. It is commonly used in oncology to monitor treatment response and to support follow-up after cancer therapy.

A Renal function panel is a group of laboratory blood tests that helps assess how well the kidneys are working. It looks at kidney filtration and related body chemistry, such as electrolytes and acid–base balance. It is commonly used in oncology to support safe treatment planning and monitoring during therapy. It is also used in general medicine for evaluating dehydration, chronic kidney disease, and medication effects.

LFTs are blood tests that help assess how the liver is functioning. They are commonly used in oncology to establish a baseline before treatment and to monitor safety during therapy. LFTs can also support evaluation when cancer may involve the liver or when symptoms suggest liver or bile-duct problems. The term “LFTs” usually refers to a panel of related lab values interpreted together, not a single test.

CMP most commonly refers to a **Comprehensive Metabolic Panel**, a group of blood tests run together. It provides a broad snapshot of **kidney function, liver function, electrolytes, blood sugar, and protein status**. In cancer care, CMP is commonly used **before, during, and after treatment** to support safe planning and monitoring. It is ordered in clinics, infusion centers, emergency settings, and during hospital care.
