| fluorescein eye examination | A special test that allows the examiner to detect cornea abrasions or corneal foreign bodies. An orange dye (fluorescein) is placed into the eye and the eye is illuminated with a cobalt blue light (black light). This serves to highlight any irregularities in the corneal surface. (27 Sep 1997) |

| fluorescein | <chemical> Fluorophore commonly used in microscopy. Fluorescein di acetate can be used as a vital stain or can be conjugated to proteins (particularly antibodies) using isothiocyanate. Excitation is at 365nm and the emitted light is green yellow (450-490nm). The emission spectrum is pH sensitive and fluorescein can therefore be used to measure pH in intracellular compartments.

| fluorescein-5-isothiocyanate | <chemical> 3',6'-dihydroxy-5-isothiocyanatospiro(isobenzofuran-1(3h),9'-(9h)xanthen)-3-one. Fluorescent probe capable of being conjugated to tissue and proteins. It is used as a label in fluorescent antibody staining procedures as well as protein- and amino acid-binding techniques. Pharmacological action: fluorescent dyes. Chemical name: Spiro(isobenzofuran-1(3H),9'-(9H)xanthen)-3-one, 3',6'-dihydroxy-5-isothiocyanato- (12 Dec 1998) |
| fluorescein angiography | <procedure> The process of taking X-rays of blood vessels that have been injected with a special dye. The dye allows to person viewing the X-ray to see the blood vessels. (13 Nov 1997) |
| fluorescein-conjugated antibody | Refers to an antibody that has joined with a fluorescein molecule. (09 Oct 1997) |
| fluorescein instillation test | A test for patency of the lacrimal system; fluorescein instilled in the conjunctival sac can be recovered from the inferior nasal meatus. Synonym: Jones' test. (05 Mar 2000) |
| fluorescein isothiocyanate | <chemical> A fluorescent chemical derived from fluorescein which is used to label proteins. (25 Jun 1999) |
| fluorescein sodium | A dye used for diagnosis of certain ocular diseases, differentiation or delineation of organ parts in surgery, and determination of circulation time. Synonym: resorcinolphthalein sodium, uranin. (05 Mar 2000) |
| fluorescein string test | A string test used to determine location of a bleeding intestinal lesion in which fluorescein is given intravenously to determine gastrointestinal haemorrhage; if the string fluoresces after removal, it has been contaminated by blood that has appeared since injection of the fluorescein; used to determine location of bleeding lesion. (05 Mar 2000) |
| 3-O-methyl-fluorescein phosphatase | <enzyme> Used for assay of na-k-atpase in intact tissues Registry number: EC 3.6.1.- Synonym: 3-o-methylfluorescein phosphatase (26 Jun 1999) |
| automobile driver examination | Government required written and driving test given to individuals prior to obtaining an operator's license. (12 Dec 1998) |
| bone marrow examination | Removal of bone marrow and evaluation of its histologic picture. (12 Dec 1998) |
| breast self-examination | <procedure> A a regular, defined process of thorough examination of the breasts once a month to detect any changes or suspicious lumps. Exams should be practiced at the end of the period or seven days after the start of the period and be performed monthly at the same time. (09 Oct 1997) |
| Papanicolaou examination | Microscopic examination of cells collected from the cervix. It is used to detect changes that may be cancer or may lead to cancer, and it can show noncancerous conditions, such as infection or inflammation. Also called pap smear. (12 Dec 1998) |
| physical examination | Systematic and thorough inspection of the patient for physical signs of disease or abnormality. (12 Dec 1998) |
| postmortem examination | <procedure> A surgical procedure, postmortem, which involves the examination of body tissues, often to determine cause of death. (02 Jan 1998) |
