Apr 12, 2020 · Many refractometers, such as the one depicted here, has specific gravity scales for urine in cats (left scale) and dogs (middle scale). The third scale is for total protein measurement on serum, plasma or body cavity fluids.

Read the refractometer to determine the plasma protein. If the distinction between the blue and the white is blurry this can mean that there is insufficient plasma on the reading plate. Try pressing the lid down firmly as this can make the line clearer. Refractometers may have 2 …

Plasma protein assays can be performed either using a refractometer or an automated biochemistry analyser. Total plasma protein can be measured using the plasma present in a capillary tube or sample container that has been centrifuged.

This is measured by refractometer and actually measures refractive index versus total protein. It is used as an estimate for total protein (which are the constituents of plasma that have the most effect on the refractive index).

Modern refractometers measure total protein (TP) by the refraction produced by the total dissolved solids in plasma and have been calibrated to subtract 2.0 g/dL of the expected non-protein solids in plasma.

Refractometer TPP<58 g/L (<5.8 g/dL) predicted serum total protein of <40 g/L (<40 g/dL) with sensitivity of 82% and specificity of 84%.

Refractometers have been used for more than half a century to provide a simple and fast method of assessing serum total protein concentration. The MISCO Palm Abbe™ Refractometer is the Toughest, Most Precise Digital Refractometer Anywhere!

Refractometer TPPo58 g/L (o5.8 g/dL) predicted serum total protein of o40 g/L (o40 g/dL) with sensitivity of 82% and specificity of 84%.

Nov 25, 2022 · Total protein determination using a refractometer is a quick, inexpensive, and extremely valuable in-house test. Measuring the plasma total protein value is necessary to fully interpret the packed cell volume (PCV), complete blood count (CBC), and urinalysis findings.

Refractometers are ubiquitously used in veterinary clinics to provide rapid, easy, inexpensive assessment of protein concentration in plasma and other fluids.
