Tests
Platelets, also known as thrombocytes, are small blood cells. They form in your bone marrow, the sponge-like tissue in your bones. Platelets are essential for blood clotting . A blood clot is a mass of blood that forms when platelets, proteins, and cells in the blood stick together. When you get hurt, your body forms a blood clot to stop the bleeding.
Tests
Porphyrin tests measure the level of porphyrins in your blood, urine (pee), or stool (poop). Your body uses porphyrins to make heme. Heme is part of hemoglobin, which is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body.
Tests
A prealbumin blood test measures prealbumin levels in your blood. Prealbumin is a protein that's made in your liver and is found in your blood. Prealbumin is used to make other proteins and helps carry thyroid hormones and vitamin A through your bloodstream. It also helps control how your body uses energy.
Tests
The determination of the amount of pregnancy-associated plasma protein-A present in a sample.
Tests
The determination of the amount of the prostaglandin D2 synthase in a sample.
Tests
A protein produced by prostate tissue; elevated values can reflect prostate cancer but also common benign conditions.
Tests
Protein C and protein S tests use a sample of your blood to measure how many of these proteins you have and how well they're working. Though they are often done together, these are separate tests. A protein C test measures protein C in your blood ; a protein S test measures protein S.
Tests
A protein in urine test measures how much protein is in your urine (pee). Normally, you have very little protein in your urine. A large amount of protein in urine (proteinuria) may mean you have a kidney problem . Your kidneys are organs that filter extra water and waste out of your blood to make urine.
Tests
The determination of the ratio of the biological activity of protein S in a subject's specimen when compared to the same activity in a control specimen. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of total protein compared to creatinine present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
A measurement of the protein Wnt-10b activity in a sample.
Tests
A red blood cell (RBC) count measures the number of red blood cells, also known as erythrocytes, in your blood. Red blood cells are made in your bone marrow, the spongy tissue inside your large bones. They contain hemoglobin, an iron-rich protein that carries oxygen from your lungs to every cell in your body. Your cells need oxygen to grow, reproduce, and make energy for you to function. An RBC count that is higher or lower than normal is often the first sign of an illness. So, the test may allow you to get treatment even before you have symptoms.
