Lab Tests Beginning With N
4 tests in the Lab Values reference begin with the letter N. Every name links to a page with its typical adult range in both unit systems, plain-language notes on high and low results, and preparation notes where they apply.
A B C D E F G H I L M N NUMBERS O P R S T U V W Z
| Test | Abbr. | Typical range (conventional) | Typical range (SI) |
|---|---|---|---|
| Neutrophils % | — | 55–70 % | 55–70 % |
| Non-HDL Cholesterol | — | Desirable <130 mg/dL | Desirable <3.37 mmol/L |
| NT-proBNP | — | <125 pg/mL | <15 pmol/L |

Please note: Reference ranges vary between laboratories, and between the methods and instruments they use — the range printed on your own report is the one your result should be compared with. A result outside the range is not by itself a diagnosis, and a result inside it does not rule out illness. These pages are an educational summary, not medical advice: always discuss your results with the clinician who ordered them, who can interpret them in the context of your health and history.
