Protein S Measurement: Purpose, Procedure, and Results

A protein S measurement is a test used to measure the amount of protein S in your body. This protein plays a role in controlling the blood clotting process.

Protein C and Protein S – Lab Tests Online

There are three types of inherited protein S deficiencies associated with being heterozygous for protein S deficiency. People who are heterozygous for protein S deficiency have a 10 fold increased risk for VTE. Results that may be seen with the three types of deficiency are summarized below. The most common types are 1 and 3.

C-Reactive Protein Test: Purpose, Procedure, and Results

A C-reactive protein test, or CRP test, is a blood test that measures the amount of CRP in your blood. A high level of CRP can mark inflammation and be caused by a variety of conditions, from

Overview of Protein Assays Methods | Thermo Fisher

Depending on the sample type and purpose for performing an assay, protein-to-protein variation is an important consideration in selecting a protein assay method and in selecting an appropriate assay standard (e.g., BSA vs. BGG). Protein assay methods based on similar chemistry have similar protein-to-protein variation.


The advantages of this method are that the procedure is simple to carry out, it is nondestructive, and no special reagents are required. The major disadvantage is that nucleic acids also absorb strongly at 280 nm and could therefore interfere with the measurement of the protein if …


Protein Analysis-Determination of Protein Concentration

purpose of using both values is to correct for nucleic acid contamination in protein samples. The Lowry procedure was developed in 1951 as a sensitive method of analysis, and it has since become the most cited scientific paper.

Total Serum Protein Test & Albumin to Globulin (A/G) Ratio

The total serum protein test measures all the proteins in your blood. It can also check the amount of albumin you have compared to globulin, or what’s called your “A/G ratio.”

Creatinine blood test: Purpose, procedure, and low or high

What is the purpose of the test? A creatinine blood test measures kidney function. The body produces creatinine at a steady rate, and measuring the levels only requires a routine blood sample.

To estimate the amount of protein in the given sample by Bradford Assay. Principle The protein in solution can be measured quantitatively by different methods. The methods described by Bradford uses a different concept-the protein‘s capacity to bind to a dye, quantitatively. The assay is based on the

24-Hour Urine Collection | Johns Hopkins Medicine Health

A 24-hour urine collection is a simple lab test that measures what’s in your urine. The test is used to check kidney function. A 24-hour urine collection is done by collecting your urine in a special container over a full 24-hour period.

Urine Protein – Lab Tests Online

Urine protein testing is used to detect protein in the urine (proteinuria). A semi-quanititative test such as a dipstick urine protein may be used to screen people for the presence of protein in the urine as part of a routine urinalysis.

Serum Osmolality Blood Test: Purpose, Procedure, and Results

A serum osmolality test is a way to check the fluid balance in your body. It can help your doctor diagnose several possible conditions. You may also hear it called an “osmolality serum” test.

How to Measure Protein Concentration More Accurately

Choosing the right technique for your protein will take a bit of trial and error, but having a good technique in your back pocket to accurately measure your protein concentration will save you a lot of time and energy and help you get more reproducible results.
