Indicators
Hemoglobin where the heme group has formed a stable complex with carbon monoxide (CO). This complex is produced after CO has been inhaled or as a byproduct of hemoglobin, protoporphyrin or dichloromethane catabolism. The heme-CO complex is approximately 200 times more stable than heme-oxygen complexes. Thus, high levels of carboxyhemoglobin in the circulation can lead to tissue hypoxia and death.
Glossary Term
A study that compares two groups of people: those with the disease or condition under study (cases) and a very similar group of people who do not have the disease or condition (controls). Researchers study the medical and lifestyle histories of the people in each group to learn what factors may be associated with the disease or condition. For example, one group may have been exposed to a particular substance that the other was not. Also called retrospective study.

Glossary Term
A research study that compares a particular outcome (such as lung cancer) in groups of individuals who are alike in many ways but differ by a certain characteristic (for example, female nurses who smoke compared with those who do not smoke).
Tests
A complement blood test measures the levels and/or activity of a group of proteins that are part of the complement system. This system "complements" or enhances your body's defenses against infections and other diseases. Your immune system makes antibodies, which are proteins to fight disease-causing substances like viruses and bacteria. The proteins in the complement system will also help fight the infection or disease. These proteins work together in a sequence, with one protein activating the next.
Tests
A complete blood count, or CBC, is a group of blood tests that measure the number and size of the different cells in your blood. A CBC measures:
Glossary Term
A nucleotide comprised of either a purine or pyrimidine nitrogenous base bound to a deoxyribose sugar esterified with three phosphate groups. These molecules are essential for DNA synthesis.
Article
Research record from Clin Microbiol Infect, 2026-07-10. PMID 42431400.
Indicators
This gene is involved in nucleotide excision repair and corrects sensitivity to UV radiation and defective nucleotide excision repair in xeroderma pigmentosum cells of complementation group D.
Tests
The determination of the antigen from Escherichia coli K1 and/or Neisseria meningitidis serogroup B in a sample.
Indicators
This gene may be involved in the mediation of DNA repair.
Indicators
This gene may play a role in DNA cross-link repair.
