Different references answer different questions. Occupational databases describe work and preparation; an accrediting agency identifies education programs; professional societies explain their own fields; government agencies describe tests, oversight and safety. The entries below state what each source covers, so the next reading can follow the question rather than the organization’s name.

Blood and transfusion
American Red Cross: blood types — Explains antigens, blood groups and the importance of typing and cross-matching for transfusion. It is background on compatibility testing rather than a substitute for laboratory decisions.
American Red Cross: blood supply — Describes the need for blood and the components used in care. Whole blood, red cells, platelets and plasma appear in its account of the supply.
FDA: blood and blood products — Describes federal oversight of blood collection, blood components and related products. Standards, inspections and monitoring of reported problems are part of the regulatory account.
Laboratory tests explained
MedlinePlus: laboratory test topics — A general introduction to laboratory testing with links organized around tests and related topics. It places an unfamiliar test name within a wider subject.
MedlinePlus: understanding laboratory results — Explains laboratory samples, results and reference ranges. Its discussion shows why a measurement is considered with other health information rather than read as a diagnosis by itself.
MedlinePlus: blood testing — Describes blood tests as measurements of cells, chemicals, proteins and other substances. It introduces common categories of testing and the collection process.
MedlinePlus: complete blood count — Describes a group of tests examining blood cells and related measurements. It distinguishes the overall count from further detail provided by a differential.
MedlinePlus: blood differential — Explains measuring the amount of each type of white blood cell. The description connects the count with the different cell types involved in immune function.
MedlinePlus: basic metabolic panel — Introduces grouped blood chemistry measurements, including glucose and minerals. Its explanation connects the panel with metabolism, body fluids and kidney-related information.
MedlinePlus: comprehensive metabolic panel — Describes a broader group of blood chemistry measurements. The page explains the substances included and how the panel supplies information about metabolism and body chemistry.
MedlinePlus: cholesterol testing — Explains measuring cholesterol and triglycerides in blood. The laboratory subject is a set of fat-related measurements rather than a direct measurement of an eating habit.
MedlinePlus: hemoglobin A1C — Explains how this blood test reflects average glucose over time. It distinguishes that subject from the glucose concentration measured in a sample at a particular moment.
MedlinePlus: insulin in blood — Describes measuring insulin in a blood sample and identifies the pancreas as its source. The page also explains why doctors use this hormone measurement in investigations.
MedlinePlus: C-peptide — Explains C-peptide measurement in blood or urine. It describes the molecule’s relationship to natural insulin production, which is why the analyte matters in laboratory work.
MedlinePlus: growth hormone tests — Describes blood tests examining growth hormone production. Its explanation identifies the pituitary gland and places the measurement within a broader hormone investigation.
