English to Romanian Medical Medical: Pharmaceuticals Chemistry

Buna ziua,

As avea nevoie de ajutor pentru traducerea structurii "blank plasma" in limba romana.
Aceasta imi apare in urmatorul context:
"The quantitative applicability of the method was validated by six-point calibration standard curves over the range of 0.05–5.0g/ml for AT and RT, 0.05–2.0 g/ml for MT by adding solutions of AT, RT and MT to 200l blank plasma. The quality control (QC) samples were prepared using different solutions of the analytes to obtain plasma concentrations of 0.1, 1.5, 4.5g/ml for AT and RT, 0.1, 0.5, 1.5 g/ml for MT representing low, medium and high concentration of QC samples, respectively."

Va multumesc anticipat pt. orice ajutor acordat!
