It is still somewhat controversial whether a positive antibody without EGD is enough to warrant eradication therapy ;

* AIDS-related complex, a condition in which antibody tests are positive for HIV

A positive screen warrants an antibody panel / investigation to determine if it is clinically significant.

Two specific antibodies are used, one conjugated with enzyme and the other present in serum ( if serum is positive for the antibody ).

Only half the patients presenting with the symptoms held by mononucleosis and a positive heterophile antibody test ( monospot test ) meet the entire criteria.

Dusty was euthanised on 31 July 2011 following a second positive antibody test.

On 15 October 2011 another horse on the property was euthanised following a positive HeV antibody test.

It is therefore not possible to conclude that blood rejected for transfusion because of a positive ELISA antibody test is in fact infected with HIV.

: HIV antibody tests are highly sensitive, meaning they react preferentially with HIV antibodies, but not all positive or inconclusive HIV ELISA tests mean the person is infected by HIV.

HIV antibody tests exceed the performance of most other infectious disease tests in both sensitivity ( the ability of the screening test to give a positive finding when the person tested truly has the disease ) and specificity ( the ability of the test to give a negative finding when the subjects tested are free of the disease under study ).

* Preceding streptococcal infection: recent scarlet fever, raised antistreptolysin O or other streptococcal antibody titre, or positive throat culture.

Occasionally, the physician will take an EBV antibody test to determine the presence of EBV, but they are not necessary if symptoms of mononucleosis are apparent and the Monospot test is positive.

Generally they have a few more gradations than just two outcomes, positive or negative, e. g. scoring on a scale of 1 + to 4 + as used for blood grouping tests based on RBC agglutination in response to grouping reagents ( antibody against blood group antigens ).

#** Coxiella burnetii detected by at least one positive blood culture or antiphase I IgG antibody titer > 1: 800

Kittens and young cats that test positive for the FIV antibody may test negative at a later time due to seroreversion, provided they have never been infected with FIV and have never been immunized with the FIV vaccine.

Cats that have been vaccinated will test positive for the FIV antibody for the rest of their life due to seroconversion, even though they are not infected.

For these reasons, a positive FIV antibody test by itself should never be used as a criterion for euthanasia.

Because of its relation to gut-associated lymphoid tissue ( GALT ), L. acidophilus LA-5 has been associated with positive effects on the immune system such as increased cytokine, phagocytic activity and antibody production, as well as phagocytosis of Salmonella, and L. acidophilus NCFM has even been shown to reduce incidence of symptoms of fever, cough and runny nose.

:* Hepatitis B or Hepatitis C virus tests positive ( for surface antigen or antibody ).

There is a lack of immune deposits on staining, but blood tests are positive for ANCA antibody.

The Sapporo criteria specify that both serological and functional tests must be positive to diagnose the antiphospholipid antibody syndrome.

A drawback to pre-partum administration of RhIG is that it causes a positive antibody screen when the mother is tested, which can be difficult to distinguish from natural immunological responses that result in antibody production.

Nodules are associated with a positive RF ( rheumatoid factor ) titer and severe erosive arthritis.

The Widal test is positive if TO antigen titer is more than 1: 160 in an active infection, or if TH antigen titer is more than 1: 160 in past infection or in immunized persons.

The titer corresponds to the highest dilution factor that still yields a positive reading.

For example, positive readings in the first 8 serial twofold dilutions translate into a titer of 1: 256 ( i. e., 2 < sup >− 8 </ sup >).

A positive test indicates that the chemical is mutagenic and therefore may act as a carcinogen, since cancer is often linked to mutation.

When pointing the thumb away from the origin along an axis, the curvature of the fingers indicates a positive rotation along that axis.

These digits are often used with a decimal separator which indicates the start of a fractional part, and with a symbol such as the plus sign + ( for positive ) or minus sign − ( for negative ) adjacent to the numeral to indicate whether it is greater or less than zero, respectively.

One of the more recent citations in the Oxford English Dictionary indicates that, while today honeymoon has a positive meaning, the word was originally a reference to the inevitable waning of love like a phase of the moon.

A positive skew indicates that the tail on the right side is longer than the left side and the bulk of the values lie to the left of the mean.

The light half-circle indicates people experiencing the results of positive actions.

Standard economic theory and empirical data indicates that second-hand clothing import can have positive effects in a country like Zambia ( one of the least developed countries in the world ).

The formation of bubbles, oxygen, indicates a positive result.

Thus, a large positive return loss indicates the reflected power is small relative to the incident power, which indicates good impedance match from source to load.

Full employability indicates an attempt by government to make people " employable " by both positive means ( e. g. training courses ) and negative means ( e. g. cuts in benefits ).

Note that the flux of E through a closed surface is not always zero ; this indicates the presence of " electric monopoles ", that is, free positive or negative charges.

This indicates that the charge in the proton is concentrated in small lumps, reminiscent of Rutherford's discovery that the positive charge in an atom is concentrated at the nucleus.

The right-hand rule indicates the positive direction of the angular velocity pseudovector.

# Average weekly jobless claims for unemployment insurance — The CB reverses the value of this component from positive to negative because a positive reading indicates a loss in jobs.

N is a positive whole number greater than 1, and it indicates the number of filter sections.

This indicates a positive trend for the District, although one which will need to reevaluated when the 2008-2009 data become available to determine whether it is part of a larger pattern or not.

Recent research indicates that inflating students ' self-esteem in and of itself has no positive effect on grades.

For example SIRS and a positive blood culture for a pathogen indicates the presence of sepsis.

The bar over the characteristic indicates that it is negative whilst the mantissa remains positive.

The VEP nomenclature is determined by using capital letters stating whether the peak is positive ( P ) or negative ( N ) followed by a number which indicates the average peak latency for that particular wave.

A positive value indicates that the object was perceived bigger and thus corresponds to macropsia, and conversely a negative value indicates micropsia.
