Reference ranges vary by labs. In some assays, 35 IU/mL is still considered the upper limit of normal. The reason for the dramatic difference in reference ranges is the detection limit of the assay itself. As time progresses, assays become more sensitive to small titers of antibody. In labs using newer techniques, concentrations as low as 9 IU/mL can be ...

While the measured quantities are the same across border, both names and units can vary. The main difference is often the unit used for the concentration of each analyte : either mass per volume or mole per volume (eg: glucose 1g/L = 5.5 mmol/L), sometime variation on the unit prefix (eg: haemoglobin 120 g/L = 12 g/dL). It is of course possible to convert a ...

A full radiology report typically contains several sections, similar to a progress note. The "HISTORY" section discusses the medical history and possibly indications for the imaging. Here, r/o means neither "has been ruled out" nor "should be ruled out in the future". It means the patient has such and such a history and this imaging test was done in order ...

NOTE: I cannot give you any references in english, since the documentation I have to backup these claims is in Portuguese. Do medical laboratories determine accuracies for their blood tests that have numerical results? In order for a lab to be certified (in my country at least, but I reckon this is probably true for other countries), periodic ...

Short answer? Most likely none. Better answer? What you are asking is what we health professionals call "Screening tests", which are by definition highly sensitive but relatively non-specific routine tests that are cost-effective to conduct routinely in HEALTHY population at risk for a particular disease. Things like Prostate Antigen or Occult Blood in ...

The information you provided Right lens Sph -0,50 Cyl -0,50 axis 10 Left Lens Sph -0,50 Cyl -0,50 axis 170 Type CR39 SN ARC is a little bit clearer than you can sometimes see. When you look at your prescription for eyeglasses, you can sometimes see numbers listed under the prefixes of OS and OD, or OU. They are Latin abbreviations: OS (oculus ...

Cells of the blood are produced in the bone marrow by multiple steps of differentiation, yielding intermediate precursor cells like metamyelocytes. Their presence in peripheral blood is abnormal. This is called myelocytosis or myelemia. Myelocytosis is very concerning if there is presence of morphologically abnormal cells (like blast), especially if other ...

First, tuberculosis is caused by a bacterium, not by a virus. There are a number of different skin tests used for tuberculosis. The common ones are the Mantoux test, the tine test, and the no-longer-used Heaf test. All three of them indicate potential tuberculosis infection by measuring the presence and/or size of the firm raised area at the injection ...

Your doctor may use the term "possible lupus" if you meet part, but not all of the diagnostic criteria for lupus [1]. I'm assuming in the remainder of this post that you do not meet criteria for "probable" lupus (>= 4 criteria including 1 clinical and 1 immunologic criteria). A positive ANA is considered 1 immunologic criteria for the diagnosis of lupus. ...

Those test results indicate a positive result for traces of Helicobacter pylori in the sample given. No-one on here will give you any more medical advice. Go see your doctor with those results.

BRCA1 and BRCA2 are the names of genes that every human has1, located on chromosome 17. These genes code for proteins that suppress tumors. However, in some humans these genes carry mutations that mean that the tumor suppressing function doesn't work as well or at all. That's what people usually mean when they say that they "have" BRCA1/2, even though it's ...

Because you have to remember that coronavirus is just something added to all the different diseases that existed 6 months ago. There are tons of bacteria, virus, fungi whose infection could resemble COVID-19 sindrome (i remind you that symptoms can vary and the same symptom can present differently in different patients) that can be treated with simple ...

See long answer for How accurate are coronavirus tests? With the "worst-case numbers" from there which I take from the minimum performance requirements the FDA currently uses with an emergency validation to allow labs to quickly implement Covid-19 tests without undergoing the full validation procedure they normally take, we have LR+ ≈ 11 and LR- ≈ 1/20. ...

You can find a sample format for NCS/EMG here The report template below is based on the AANEM’s educational paper Reporting the Results of Needle EMG and Nerve Conduction Studies. A report template helps the EDX physician adhere to and document required procedures —by checking them off a list. This process will help the EDX physician complete a ...

The increased WBC, platelet, and Neutroplil count suggests that your body may be trying to fight off an infection. When the body is under attack, it increases it's white blood cell production to combat the infection. The platelets also suggest an infection, as well as the Neutrophil count, which are a type of white blood cell. The possibility of illness is ...
