Normal range: Negative

Comment: Test is helpful in supporting the diagnosis of infection with Schistosoma spp. especially when the eggs cannot be demonstrated in the faeces or urine. Presence of antibodies is indicative of schistosoma but cannot be correlated with worm burden, egg production, clinical status or prognosis. Current infection is associated with a rising titer. Titer can remain high for some years after infection. Cross-reactions may occur with other parasitic diseases, including hydatid infection

Sample: Serum

:Therapeutic range

            150-300mg/L as anti-inflammatory

100for mg/L analgasia and anti platelets>

Comment: Measured to check therapeutic effect or toxicity. There is a good correlation between plasma levels and response to treatment in rheumatic fever

Sample: Serum, urine

Normal range: Negative

Comment: IgM specific antibody appears about 14 days after infection peaks rapidly and then falls gradually to low levels within a month, persisting up to nine months

Sample: serum

:Normal range

Not immune: Negative

Previous exposure: Positive

(Comment: Fetal infection during the first trimester is main concern for such test. (Do not vaccinate in suspected pregnancy

Sample: serum

Normal range: Negative

Comment: Rotavirus is transmitted by the fecal-oral route and is responsible for epidemic diarrhea infections, especially in children. Can be detected by antigen detection, culture or electron microscopy. Antibody measurement in serum is not advised as raised levels are found

in the normal population

Sample: Stool, fresh

Normal range: Negative

Comment: RF are autoantibodies directed against the Fc fragment of IgG. These are usually IgM, but may be IgG or IgA. Found in majority of rheumatoid arthritis patients and some other conditions including Felty’s syndrome, Sjogren’s syndrome

Sample: serum

Normal range: Negative

Comment: of particular importance in Rh negative antenatal patients. Identification and titer carried out if antibody detected. Regular checks should be made during pregnancy, especially towards term. If levels are very high an amniocentesis for bilirubin should be carried out

Sample: serum

Sample: serum

Normal range: 0.5-2.0%

Comment: Increased in hemolysis and after blood loss, and during the   first week of responding to such hematinics as iron, B12 and folate. They are decreased to virtually undetectable levels in congenital red cell aplasia, most cases of aplastic anemia and after bone marrow transplantation

Sample: EDTA whole blood

Normal range: Negative

Comment: Patients with upper or lower respiratory tract infection may present with atypical presentation that may not respond to usual antibiotics, or may have persistent cough or unresolved pneumonic shadows in the lung. Respiratory tract infection can screen for the most common viral and bacterial infections that affect the respiratory tract
