This study forms part of Entia's clinical evidence for regulatory submission. This study evaluates Entia Liberty's performance claims with venous blood compared to the gold standard clinical laboratory haematology analysers. Excess blood flagged by the laboratory meeting our requirements will be tested on the Entia Liberty device and have its results compared against the laboratory results. Samples will also be flagged for precision testing (same blood sample, split into 10 Entia Liberty samples).

Inclusion Criteria:

• Age >18 years old
• Currently receiving standard of care systemic anti-cancer therapy (chemotherapy, immunotherapy, endocrine and targeted therapy) for solid organ malignancy and has received at least one cycle
• Blood samples that have been stored in K2-EDTA vacutainers only
• For Accuracy testing: Samples covering 75% of parameter ranges (Neutrophils: 0.5-7.5 x 109/L, Platelets: 20-450 x 109/L, Haemoglobin: 70-180 g/L), These will be determined by a gold standard analyser which has been recently calibrated.
• Reliability study: Level range per parameter. These will be determined by a gold standard analyser which has been recently calibrated.
• Neutrophils (We assume WBC to behave similarly in the same ranges) Low: 0.5-1.2 x 109/L (3 samples), 1.2-2 x 109/L (2 samples) Normal: 2-7 x 109/L (3-4 samples) High: 7-12 x 109/L (1-2 samples)
• Platelets Low: 50-150 x 109/L (5 samples) Normal: 150-400 x 109/L (3 - 4 samples) High: >400 x 109/L (1-2 samples)
• Haemoglobin Low: <120 g/L (5 samples) Normal: 120-170 g/L (3 - 4 samples) High: >170 g/L (1-2 samples)

Exclusion Criteria:

• History of haematological malignancy

No participants will be recruited. Samples used are from excess venous bloods from the Christie haematology laboratory
