| lepromin reaction | A delayed hypersensitivity reaction at the site of an intradermal injection of a lepromin, such as the Dharmendra antigen or Mitsuda antigen, in a lepromin test; the reaction's, such as the Fernandez or Mitsuda reaction, are variable, occurring in 48 hours or three to five weeks, but are uniformly negative in lepromatous leprosy, borderline leprosy, and mid-borderline leprosy.

| furfurol reaction | Production of a red colour on addition of furfurol to a solution of aniline. (05 Mar 2000) |
| leukemoid reaction | A benign blood picture resembling leukaemia. For example, in infectious mononucleosis. (12 Dec 1998) |
| lid-closure reaction | A constriction of both pupils when an effort is made to close eyelids forcibly held apart. A variant of the pupil response to near vision. Synonym: Galassi's pupillary phenomenon, Gifford's reflex, lid-closure reaction, orbicularis phenomenon, orbicularis pupillary reflex, Piltz sign, Westphal's pupillary reflex, Westphal-Piltz phenomenon.

| ligase amplification reaction | <molecular biology> Method for detecting small quantities of a target DNA, with utility similar to PCR. It relies on DNA ligase to join adjacent synthetic oligonucleotides after they have bound the target DNA. Their small size means that they are destabilised by single base mismatches and so form a sensitive test for the presence of mutations in the target sequence. (18 Nov 1997) |
| light dependent reaction | The reaction taking place in the chloroplast in which the absorption of a photon leads to the formation of ATP and NADPH. (18 Nov 1997) |
| local anaesthetic reaction | A toxic reaction due to absorption of local anaesthetic drug during regional anaesthesia, ranging from drowsiness to convulsions and cardiovascular collapse. (05 Mar 2000) |
| local reaction | A reaction which occurs at the point of entrance of an infecting organism or of an injection, as in the Arthus phenomenon. Synonym: local reaction. (05 Mar 2000) |
| Loewenthal's reaction | The agglutinative reaction in relapsing fever. (05 Mar 2000) |
| Lohmann reaction | The reaction catalyzed by creatine kinase. (05 Mar 2000) |
| lymphocytic leukemoid reaction | Leukocytosis of varying degree, with adult lymphocytes and immature forms amounting to 40% (or more) of the total number of white blood cells in the circulating blood; may be observed in association with pertussis, infectious mononucleosis, gonorrhoea, chickenpox, and sarcoidosis.
