Indicators
Lactotransferrin (710 aa, ~78 kDa) is encoded by the human LTF gene. This protein is involved in the mediation of both proteolysis and iron transport.

Tests
Legionella is a type of bacteria . When it affects your lungs, it can cause a severe form of pneumonia known as Legionnaires' disease . Legionella tests look for these bacteria in urine, sputum, or in some cases in lung tissue. A blood test may be done to check if you have been exposed to the bacteria, but it cannot diagnose a Legionella infection.
Indicators
Leptin (167 aa, ~16 kDa) is encoded by the human LEP gene. This protein is secreted by adipocytes and plays a role in the regulation of both appetite and body fat stores.
Glossary Term
Major class of enzymes that catalyze the linking together of two molecules (EC class 6) for example DNA ligases that link two fragments of DNA by forming a phosphodiester bond.
Glossary Term
A molecule of RNA 200-17000 nucleotides in length that is transcribed by non-protein coding areas of DNA. These ribonucleotides may play a role in a variety of biological processes.
Tests
A proprietary PCR technique that uses a pool of primers to amplify a 450 bp region in the L1 region of the HPV genome. It is capable of detecting 37 high- and low-risk human papillomavirus genotypes.
Glossary Term
The formula to calculate body surface area as described by John D. Current. It is mathematically defined as: BSA (m^2) = 1321 + 0.3433 x Weight(g)
Tests
A lipase test measures the level of lipase in your blood. Lipase helps your body digest fats . It's a type of digestive enzyme. An enzyme is a protein that speeds up certain chemical reactions in your body. Most of your lipase is made in your pancreas, an organ located behind the lower part of your stomach. Lipase is also made in your salivary (spit) glands and in your stomach.
Tests
A lipoprotein (a) test measures the level of lipoprotein (a) in your blood. A high level of lipoprotein (a) may mean you have a high risk for heart disease and stroke .
Indicators
Lipoprotein lipase (475 aa, ~53 kDa) is encoded by the human LPL gene. This protein is involved in the metabolism of triglycerides.
