Plosone

No correlation to the infecting strain serotypes was apparent, nor was there any obvious correlation to SBA titres (most of the acute sera had high levels of complement independent killing so an SBA titre could not be obtained).

Expert writing Tips

Best practice

When discussing changes in "levels of complement", specify whether the levels are increasing or decreasing to provide clarity.

Common error

Avoid ambiguity by clearly stating which complement components (e.g., C3, C4, factor H) you are referring to, rather than simply stating "levels of complement".

Linguistic Context

The phrase "levels of complement" functions as a noun phrase, typically acting as the subject or object of a sentence. It refers to the measured quantity or concentration of complement proteins in a biological sample. Ludwig provides numerous examples demonstrating this usage in scientific and medical contexts.

FAQs

What factors can affect the "levels of complement"?

Factors such as age, disease state, genetic variations, and certain medications can influence the "levels of complement" in the body.

What does it mean if my "levels of complement" are low?

Low "levels of complement" can indicate an over-activation of the complement system, consumption due to immune complex formation, or a deficiency in complement protein production. Certain medical conditions are associated with reduced complement levels.

How are "levels of complement" measured?

Levels of complement components are typically measured through blood tests, using methods like nephelometry or ELISA assays, which quantify the amount of specific complement proteins present in the sample.

Are there alternative ways to say "levels of complement"?

Yes, you can use phrases like "complement component concentrations", "complement protein quantities", or "complement system activity" depending on the specific context.
