Specific Gravity Test الكثافة النوعية للبول

 

الكثافة النوعية للبول 

الكثافة النوعية او الوزن النوعى : هي أحد الاختبارات الفيزيائية  التي يتم إجراؤها أثناء تحليل البول الروتيني.

الكثافة النوعية عبارة عن  كثافة (أو وزن) عينة البول مقارنةً بكثافة (وزن) الماء المقطر عند نفس درجة الحرارة.

Specific Gravity of urine | Urinometer-Refractometer

Specific gravity test

Specific gravity 

Specific gravity measurements are one of the physical examinations performed during a routine urinalysis.
Urine specific gravity is defined as the density (or weight) of the urine specimen as compared to the density (weight) of distilled water at the same temperature.
The density of the urine specimen is dependent on the
amount and size of the dissolved substances present
in the urine specimen. 
These include such substances as glucose, proteins, and electrolytes. The kidneys are responsible for selective reabsorption of essential chemicals and fluid after the blood is filtered. 
Abnormal specific gravity values may be an early indication of renal dysfunction. 
Low specific gravity urine is considered to be dilute with very few dissolved substances, whereas urine with a high specific gravity indicates that the urine is concentrated with increased amounts of dissolved substances. 

خطه شاملة لتطوير نفسك فى مجال التحاليل الطبيه



دلوقتى لو واحد مبتدئ عاوز خطه يمشي عليها لتطوير نفسه فى مجال التحاليل الطبيه بشكل يمكنه من ممارسه المهنه باحترافيه ... يعمل ايه؟؟؟؟؟؟؟؟
حنحاول فى البوست ده الاجابه على السؤال بشكل علمى موضوعى قابل للتنفيذ
اولا حنقسم الشغل فى مجال التحاليل الطبيه الى قسمين
***** القسم الاول و هو الشغل العملي:
=====================
و ده الجزء الاساسي لاى مشتغل بالتحاليل (سواء اخصائي او فنى) لان بدونه يبقي انت متقدرش تمارس المهنه
الجزء ده ملوش حل غير انك تقف فعليا فى معمل لممارسه المهنه و التي تشمل الاتى
1- التدريب على سحب العينات (بالممارسه الفعليه كلما امكن)
2- التدريب على شغل الاستقبال من مقابله مرضى و قراءه ريكوست و غيره (يحتاج ممارسه حوالى شهر متواصل)
3- التدريب على شغل الكيمياء (يحتاج ممارسه حوالى شهر متواصل بشرط يكون المعمل ذو ريت متوسط على الاقل)
4- التدريب على شغل الميكروبيولوجى و الباراسيتولوجى (يحتاج ممارسه حوالى 5 شهور بشرط يكون المعمل ذو ريت متوسط على الاقل)
5- التدريب علي شغل الهيماتولوجى (يحتاج ممارسه حوالى 5 شهور مع ضروره التدريب على فيلم الدم و الشغل المانيوال لصوره الدم)
لازم نعرف كويس ان من المستحيل تلاقي معمل يقبل يدرب حد المده دى (حوالى سنه) لمجرد التدريب انما ده حيتم لما تقدم فى معمل و تشتغل فعليا فاعمل لنفسك الخطه الزمنيه دى عشان تتعلم صح
الحل البديل ان النقابه مثلا تتبنى موضوع التدريب العملى لأعضاء شعبه العلوم الطبيه عن طريق تجهيز معمل فعلى فى مقر النقابه و تبقي سنه التدريب دى كأنها سنه امتيازمثلا
***** القسم الثانى و هو الشغل النظرى:
=====================
و ده الجزء الخاص باخصائي التحاليل الطبيه و اللازم لتفسير نتائج التحاليل الطبيه و ربطها بالحاله المرضيه و ده يقع العبء الاكبر فيه عليك و على ارادتك فى انك تصبح متميز و محترف فى المجال
و عشان يبقي كلامنا محدد حنقسم العلوم الطبيه المعمليه و نكتب مع كل قسم افضل مرجع علمى تقدر تشتغل منه و تتعلم المهنه بشكل علمى صحيح
*** علم الكيمياء الاكلينيكيه: تقدر تشتغل من مرجع
Clinical Biochemistry AN ILLUSTRATED COLOUR TEXT (Fifth Edition)
Clinical Chemistry TECHNIQUES, PRINCIPLES, CORRELATIONS (Sixth Edition)
*** علم الميكروبيولوجى (البكتريا و الفيروسات و الباراسيتولوجى و المزارع): تقدر تشتغل من مرجع
District Laboratory Practice in Tropical Countries (Monica Cheesbrough) Part 1 (Second Edition)
District Laboratory Practice in Tropical Countries (Monica Cheesbrough) Part 2 (Second Edition)
*** تحليل البول: تقدر تشتغل من مرجع

*** تحليل السائل المنوى: تقدر تشتغل من مرجع
WHO laboratory manual for the Examination and processing of human semen (Fifth Edition)
*** علم الهيماتولوجى: تقدر تشتغل من مرجع
Hematology in Practice (Betty Ciesla, 2007)
*** بعد كده عندنا مرجعين مميزين اوى لانهم بيشملوا فى كلامهم كل الفروع السابقه بشكل مبسط فممكن تستخدمهم كنوع من المراجعه و حيبقى كلامهم سهل كتير لانك قرأت قبلهم مراجع قويه جدا
Essentials of Clinical Pathology (First Edition: 2010)
A Concise Review of Clinical Laboratory Science (Second Edition)
*** و اخيرا بعد كده تقدر بكل بساطه تشتغل من كتب اسئله البورد الامريكى للتحاليل الطبيه كمراجعه للمعلومات اللى ذاكرتها قبل كده بحيث تصل لافضل مستوى علمى ممكن فى مجال التحاليل الطبيه
BOC study guide 5th edition
Medical Laboratory Science Review (Fourth Edition)
ملحوظه مفيش وقت زمنى محدد هنا لانها تعتمد على مدى رغبتك فى التعلم و كمان تعتمد على الوقت المتاح فعليا ليك

تحليل البول كامل urine analysis

تحليل البول كامل
تحليل البول كامل  Urine Analysis  
    

يعد فحص وتحليل البول من أهم الفحوصات المطلوبة كثيرا والتى يجب أن يعرف الاخصائى كل شئ عنه وفى الاونة الاخيره  يستخدم الاخصائى شرائط الغمس على نطاق واسع فى فحص البول لسهولة وسرعة إجراء الاختبارات المختلفة لكن ينصح بتحضير محاليل الفحص الكيميائية لاستخدامها فى حالة تلف الشرائط أو للتاكد من دقة الاختبارات.

Finar-OrganicChemistry book part (1)


Organic chemistry

 is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds. Most organic compounds contain carbon and hydrogen, but they may also include any number of other elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, sulfur).

Aliphatic compounds

The aliphatic hydrocarbons are subdivided into three groups of homologous series according to their state of saturation
alkanes (paraffins): aliphatic hydrocarbons without any double or triple bonds, i.e. just C-C, C-H single bonds
alkenes (olefins) aliphatic hydrocarbons that contain one or more double bonds, i.e. di-olefins (dienes) or poly-olefins.
alkynes (acetylenes) aliphatic hydrocarbons which have one or more triple bonds.
The rest of the group is classed according to the functional groups present. Such compounds can be "straight-chain", branched-chain or cyclic. The degree of branching affects characteristics, such as the octane number or cetane number in petroleum chemistry.
Both saturated (alicyclic) compounds and unsaturated compounds exist as cyclic derivatives. The most stable rings contain five or six carbon atoms, but large rings (macrocycles) and smaller rings are common. The smallest cycloalkane family is the three-membered cyclopropane ((CH2)3). Saturated cyclic compounds contain single bonds only, whereas aromatic rings have an alternating (or conjugated) double bond. Cycloalkanes do not contain multiple bonds, whereas the cycloalkenes and the cycloalkynes do.

Aromatic compounds

Benzene is one of the best-known aromatic compounds as it is one of the simplest and most stable aromatics.
Aromatic hydrocarbons contain conjugated double bonds. This means that every carbon atom in the ring is sp2 hybridized, allowing for added stability. The most important example is benzene, the structure of which was formulated by Kekulé who first proposed the delocalization or resonance principle for explaining its structure. For "conventional" cyclic compounds, aromaticity is conferred by the presence of 4n + 2 delocalized pi electrons, where n is an integer. Particular instability (antiaromaticity) is conferred by the presence of 4n conjugated pi electrons.

Heterocyclic compounds

The characteristics of the cyclic hydrocarbons are again altered if heteroatoms are present, which can exist as either substituents attached externally to the ring (exocyclic) or as a member of the ring itself (endocyclic). In the case of the latter, the ring is termed a heterocycle. Pyridine and furan are examples of aromatic heterocycles while piperidine and tetrahydrofuran are the corresponding alicyclic heterocycles. The heteroatom of heterocyclic molecules is generally oxygen, sulfur, or nitrogen, with the latter being particularly common in biochemical systems.
Heterocycles are commonly found in a wide range of products including aniline dyes and medicines. Additionally, they are prevalent in a wide range of biochemical compounds such as alkaloids, vitamins, steroids, and nucleic acids (e.g. DNA, RNA).
Rings can fuse with other rings on an edge to give polycyclic compounds. The purine nucleoside bases are notable polycyclic aromatic heterocycles. Rings can also fuse on a "corner" such that one atom (almost always carbon) has two bonds going to one ring and two to another. Such compounds are termed spiro and are important in several natural products.
