Results are usually reported in one of two ways:
- Less than 40-60 u/mL
- Less than 1:80 (1 to 80) titer
A low number (normal result) usually means you do not have rheumatoid Arthritis or Sjogren syndrome. However, some people who do have these conditions still have a "normal" or low rheumatoid factor (RF).
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

What is the full form of RF in space technology?
RF- Radio Frequency, which is in the measure of kilo & mega Hz range
Difference between RF microwave?
RF means radio frequency or relativity low range of frequency microwaves however are into the top range of the spectrum or very hi frequency.
What is range of rf transmitter and receiver?
depends on frequency and power
What is the normal level of rheumatoid factor?
A rheumatoid factor (RF) blood test measures the amount of the RF antibody present in the blood.The results of the rheumatoid factor (RF) test may be reported in titers or units:A titer is a measure of how much the blood sample can be diluted before RF can no longer be detected. A titer of 1 to 20 (1:20) means that RF can be detected when 1 part of the blood sample is diluted by up to 20 parts of a salt solution (saline). A larger second number means there is more RF in the blood. So a titer of 1 to 80 shows more RF in the blood than a titer of 1 to 20.Nephelometry units show how much light is blocked by the blood sample in the tube. A high level of RF causes the sample to be cloudy, so less light passes through the tube than when the RF level is low. So an RF level of 100 units is higher than one of 40 units.NormalThe normal values listed here-called a reference range-are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses. Also, your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values listed here may still be normal for you or your lab.You can usually get the results within 24 hours.Rheumatoid factor (RF)TitersLess than 1:80UnitsLess than 60 units per milliliter (U/mL)Check with your doctor to see what the normal range is for the lab that tested your blood.High valuesHigh RF levels may be caused by:Rheumatoid arthritis.

What frequencies falls in the range of RF waves used by commercial controlled by the?
No frequencies in that range appear on the list you provided with the question.
What is RF tracking as compared to satellites?
I'm assuming you are talking about GPS when you say "satellite." RF tracking can be directional. It takes three RF receiver stations to triangulate the position of an RF transmitter and is usually less accurate than GPS. RF is also more limited by range, so the RF tracking stations are usually required to be mobile depending on the strength of the transmission signal.
What is RF selector switch?
RF refers to 'radio frequency'. A selector switch would select a different range of radio frequencies at each of its positions. RF selector switches would be found on short wave receivers and transmitters.
