Mueller-Hinton agar
Mueller-Hinton agar is a microbiological growth medium developed by J. Howard Mueller and Jane Hinton at Harvard in 1941, now the standard medium for Kirby-Bauer disk diffusion antibiotic susceptibility testing.
Platelet aggregometry
Platelet aggregometry is a family of laboratory tests that measures platelet clumping in blood samples, usually after adding an agonist such as ADP or collagen, to diagnose platelet function disorders.
Serum Bactericidal Test
Serum Bactericidal Test (Schlichter test, SBT): broth dilution assay measuring the highest dilution of a patient's antibiotic-treated serum that kills over 99.9% of the infecting organism; used to monitor endocarditis and osteomyelitis therapy.
Viral load testing
Viral load testing measures the amount of virus in a patient's blood, reported as RNA or DNA copies per milliliter, to track infection and treatment response.
Wright–Giemsa stain
Wright–Giemsa stain (Wright-Giemsa) is a combined Romanowsky-type stain used in hematology and cytology, staining cell nuclei purple and cytoplasm blue on blood and bone marrow smears.
