Biodosimetry
Biodosimetry estimates a person's absorbed radiation dose by measuring biological markers, most often chromosome aberrations in blood lymphocytes, using calibration curves; the dicentric assay has been the gold standard since the mid-1960s.
Circulating tumor DNA analysis
Circulating tumor DNA analysis is a liquid biopsy method that detects tumor-derived DNA fragments in blood to guide cancer treatment, monitor recurrence, and screen for cancer.
Gross examination

Prussian Blue Reaction
The Prussian blue reaction, also known as Perls' stain or the iron stain, is a histochemical technique that detects ferric iron in tissues, described by Max Perls in 1867.
Thrombin generation assay
The thrombin generation assay (TGA) is a laboratory hemostasis test measuring how much thrombin plasma produces over time after coagulation is triggered, assessing both bleeding and clotting risk.
Urine culture
Urine culture is a laboratory test that grows and counts microbes from a urine sample to identify the organism causing a urinary tract infection and its antibiotic susceptibilities.
