| rate, sed | A sedimentation rate, or sed rate , is a blood test that detects and is used to monitor inflammation activity. It is measured by recording the rate at which red blood cells (rbcs) sediment in a tube over time. It increases (the rbcs sediment faster) with more inflammation. (12 Dec 1998) |

| general fertility rate | A refined measure of fertility in a population; the numerator is the number of live births in a year, the denominator is the number of females of child-bearing age, usually defined as ages 15-44 (but increasingly recognised as extending to age 49). (05 Mar 2000) |
| recurrence rate | In genetic counseling, the risk that a future offspring will be affected given some specific set of relatives of whom at least one is already affected. (05 Mar 2000) |
| case fatality rate | The proportion of individuals contracting a disease that die of that disease. (05 Mar 2000) |
| maternal death rate | The number of maternal deaths that occur as the direct result of the reproductive process per 100,000 live births. See: rate. See: maternal death. (05 Mar 2000) |
| maternal mortality rate | The number of maternal deaths related to childbearing divided by the number of live births (or by the number of live births + foetal deaths) in that year. The maternal mortality rate in the united states in 1993 (and 1994) was 0.1 per 1,000 live births, or 1 mother dying per 10,000 live births. (12 Dec 1998) |
| maximal expiratory flow rate | <chest medicine, physiology> Measurement of rate of airflow during the first liter expired after the first 200 ml have been exhausted during a forced vital capacity determination. Common abbreviations are MEFR, FEF 202-1200, and fef 0.2-1.2. Acronym: MEFR (21 Jun 2000) |
| maximal midexpiratory flow rate | Measurement of rate of airflow over the middle half of a forced vital capacity determination (from the 25 percent level to the 75 percent level). Common abbreviations are mmfr and fef 25%-75%. (12 Dec 1998) |
| glomerular filtration rate | <nephrology> Measure of the kidneys' ability to filter and remove waste products. (09 Oct 1997) |
| peak expiratory flow rate | Measurement of the maximum rate of airflow attained during a forced vital capacity determination. Common abbreviations are pefr and pfr. (12 Dec 1998) |
| peak flow rate | Maximum urinary flow rate during voiding as measured by a uroflowmeter. (05 Mar 2000) |
