“…Blood collections are implemented by vacuum blood collection tubes, disposable micro centrifuge tube, syringe, heparin, and physiological saline (0.9%). It is reported that increasing of heparin content up to 0.35 mL per 10 cm 3 does not change the results [11]. Therefore, measuring cell walls are coated with heparin less than that level in the experiments (approximately 0.15 mL per 10 cm 3 ).…”

Abstract. Lung carcinoma has become one of the malignancies whose morbidity and mortality are growing significantly. Blood is a functional body fluid, it delivers oxygen and nutrients to the other parts of the body, and it is a pathway of tumor metastasis. This paper studies the possibility of diagnosing lung carcinoma by blood dielectric spectroscopy. Comparison experiments were carried out to trace the dielectric spectroscopy of blood with and without lung carcinoma changing at different tumor stages from 100 Hz to 100 MHz. The research results show that the discrepancy of complex permittivity between rat blood with and without lung carcinoma becomes significant with tumor growing, which is worthy for clinical diagnosis.

“…[16][17][18][19] A comparative study of the electrical properties of healthy and pathological blood can lead to a better understanding of biological processes linked to diabetes and to the discovery of new methods for early diagnosis. One of the main alterations that occur in the blood in the presence of high glucose concentrations (diabetes disorders) is the glycosylation of proteins.…”

In this paper, we will show the possibility of studying physical properties and irreversible phenomena that occur in blood by applying the dielectric Kluitenberg's nonequilibrium thermodynamic theory. Namely, we shall use some recent extensions of this theory that allow to infer its main characteristic parameters from experimental measures. Applying these results to the study of normal and diabetic blood we show, by comparing them, that it is possible to determine the difference, in some details, of the amount of particular phenomena occurring inside them and give a biological meaning to these phenomena. Moreover, observing a correspondence between a particular value of the frequency for which state coefficients are equal and glucose levels we introduce an alternative diagnostic method to measure the values of the glucose in the blood by determining only this frequency value. The thermodynamic description will be completed by determining the trend of the entropy production.

“…Most research has addressed only limited aspects including electrical impedance, erythrocyte suspension, polarization effect, and haematocrit dependency [14][15][16][17][18][19][20][21][22]. Furthermore, most of the studies have been performed using blood containing anticoagulant agents from blood banks.…”

-The dielectric properties of blood are extremely important for electromagnetic medical applications such as imaging, hyperthermia and ablation. The aim of this paper is to investigate the dielectric properties of human blood and examine the effects of anti-coagulant agents over a broad frequency range. The measurements were performed using freshly extracted human blood samples with and without the added agents. The measurements were performed within 20 mins after extracting the blood sample. The obtained results demonstrate a significant variation between the dielectric properties of blood with and without anti-coagulant agents. The difference is larger in conductivity than in relative permittivity. The results also demonstrate clear variation in the dielectric properties of female and male blood samples. The findings in this paper suggest that measurements conducted on blood samples with the added agents may not represent the natural in-vivo and inter-patient variations in blood properties. In order to have an accurate representation of in-vivo blood dielectric properties, all factors should be considered carefully.
