CLIA high complexity (non-waived) rapid radiobioassay for the (in vitro) detection of ⁶⁰Co, ⁷⁵Se, ⁹⁰Sr, ¹³¹I, ¹³⁷Cs, ¹⁴⁷Pm, ⁵³Gd, ¹⁶⁹Yb, ¹⁷⁰Tm, ¹⁹²Ir, ²¹⁰Po, ²³⁸Pu, ²³⁹Pu, ²³⁵U, ²³⁸U, ²⁴¹Am, ²⁴⁴Cm, and ²⁵²Cf in human urine. This high complexity (non-waived) test comprises the use of activated charcoal to eliminate color and organic solutes from samples of human urine followed by the use of a multichannel Quantulus 1220 scintillation counter to detect and quantify alpha radiation, beta radiation and gamma radiation from (in vitro) samples of human urine. The method uses an HPGe Model GR7023 Germanium detector to quantify the activity of gamma emitters and subtract their isotopes’ contributions to the liquid scintillation spectra via a calibration factor, such that the pure beta and pure alpha emitters can be identified and quantified from the resulting liquid scintillation spectra. The high complexity (non-waived) testing methodology is described in a doctoral dissertation by Evan Bogert Crawford, Department of Environmental and Radiological Health Sciences, Colorado State University, Fort Collins, Colorado (2015).

Geissler & Associates Reference Laboratory also performs COVID-19 (RT-PCR) testing.
